Aquariums that are between 75 – 80 gallons are a great size for more experienced fish keepers – they’ll fit comfortably in most homes, but they’ll also allow for a good collection of fish, plants and even ornaments or decorations. We’ve created this guide to show you what we believe to be the best fish tanks at this size currently available on the market. But before we get into the more detailed guide, let’s start with a quick overview of what the best 75 – 80 gallon tanks are according to online reviews:

Now let’s get into the more detailed guide:

 

An introduction to 75 gallon aquariums.

The first thing to be aware of with a 75 gallon aquarium is that it’s a great size for beginners AND experienced fish keepers. Some people would describe a tank of this size as large – the reality is that 75 gallons is not actually that huge, and if you have the space for a tank of this size in your home, and you want to get serious about looking after fish – then you should absolute go for a tank of this size. But here are some important points to be aware of:

Dimensions & Weight

Looking at the most popular tanks at this size on the market currently, typical dimensions of a 75 gallon aquarium would be:

18″L x 48″W x 21″H

49″L x 21.25″Wx 19.5″H

48.5″L x 18.5″W x 21 3/8″ H

The weight will depend on the material – a glass aquarium at this size would likely weigh around 150lbs when empty, and could easily weight upwards of 800lbs when full of water. So before purchasing a tank at this size, make sure that you not only have sufficient room in your home to accommodate the dimensions outlined above, but also that you have strong enough flooring to support a tank full of water at the above weight.

Required Equipment

A 75 gal tank will require some pretty advanced equipment to keep it running and to keep all of the fish inside of the tank healthy and happy. So before we start recommending what types of fish you might want to keep in a tank of this size, here is what equipment you’ll need:

Filters

To keep a relatively large aquarium of 75 gallons in size clean, you need to make sure the filter you’re using is powerful enough to properly cycle all of the water in your tank, so it is properly removed of all toxins and other nasty stuff that might harm your fish. Some of the best filter brands we’d recommend for a tank of this size include:

  • Fluval FX 6 – this filter might seem a bit too large for a 75 gallon tank, but there is actually a great video on YouTube explaining why a filter of this type could be perfect, here is the video. 
  • Fluval 406 – this is an external canister filter and will fit on nicely to your aquarium
  • AquaClear 110 – this is a power filter and would be a great choice
  • Aqueon QuietFlow – this is a quiet but efficient filter

Heater

Similar to as with the filter, a heater needs to be large enough and powerful enough to ensure that every inch of the 75 gallons of water is heated correctly and evenly, otherwise the fish you’ve stocked might be very uncomfortable if they are tropical fish (and even worse, they could potentially die if their living conditions are not ideal). We would recommend a heater between 250 watts and 300 watts. If you need advice for a heater for a 75 gallon aquarium then here are some recommendations:

  • Fluval E 300 – we think Fluval make great heaters and filters, and this is a good choice for a 75 gal tank
  • EHEIM Jager – EHEIM are a great and trusted brand
  • Aqueon submersible – this is a well-designed and reliable heater
  • Marineland Precision – heating an aquarium can be very important for certain types of fish, and the Marineland Precision heater is great at ensuring every inch of your tank is heated evenly

Lighting/hood

If you want to evenly light every section of your aquarium, then you’ll likely need to buy some extra lighting for your tank. There will be LED lighting included in many hoods of aquariums, but don’t rely on that alone to properly light the entire area. Here are a few of our top choices for lighting:

  • Finnex planted plus – This is a pretty bright light and would be great for tropical fish as well as a planted tank
  • Aqueon Optibright – this is an LED light fixture and is a popular choice
  • Aqueon Modular LED – this is not as bright as the first 2 recommendations but it is much more energy efficient so is a good choice if you are concious of this

Stand

Many of the aquariums we recommend below include a stand, however if you’re planning to buy a stand separate from your 75 gallon fish tank then you absolutely must ensure that it will withstand the weight of your tank once it is full of water. Stainless steel or hardwood will be best for strength. We typically recommend that you look for the following with your stand:

  • Storage – a stand/cabinet combo is the ideal solution for a 75 gallon aquarium as it will provide room to store all of the important equipment you’ll need to maintain the tank. It will also provide space for fish food and any other accessories you have for your fish, so it’s very useful
  • Moisture-resistant paint – this one is pretty self-explanatory, but if you’re wanting to keep your stand looking good then you might like the look of a painted stand – that’s fine, but make sure the paint is moisture-resistant.
  • Solid top – as we mentioned above, when your tank is full of water it could be pretty heavy. So having a solid top will help to keep the aquarium sturdy and give you peace of mind that it won’t collapse.

Stocking/setup ideas (ideal fish for a 75 gallon aquarium)

You can choose from either coldwater, tropical or marine fish for your tank. First you need to decide on what type of fish you’d like to keep. Cold water fish can be pretty simple to look after – goldfish are the most popular variety of cold water fish.

Ideal tropical fish would include Bettas and Oscars.

Marine fish would include Clownfish or Angelfish.

For the ideal setup, you’ll want to keep Bettas away from other Bettas, and pick one type of tank that you want to have – marine, tropical or cold water.

How to set up your tank

The easiest way to set up your 75 gallon aquarium would be in the following order:

  • Clean everything – the glass or acrylic, the equipment provided with your tank and the stand. All you need is a cloth and warm water for this if it’s a brand new tank – if you’ve bought your tank from someone else then use white vinegar to remove stains.
  • Prepare your substrate – clean your substrate until the water you’re using to clean it is no longer turning cloudy, then add the substrate to the bottom of the tank (about an inch in height)
  • Equipment – set up all of your equipment, but don’t turn anything on yet
  • Add your water and dechlorinator
  • Cycle the tank and check ammonia, nitrate and nitrite levels weekly
  • Once ammonia and nitrite levels are meausred at 0ppm, this means the cycle has ended and you can add your fish
  • And that’s it!

Now we’ve rounded up the best 75 gallon aquariums we could find online available to buy, and included them all in this guide. Check them out below:

Betta fish tank heaters

A fun decorative touch over the recent years has been the vibrant Betta fish in small single fish aquariums.  While beautiful and fun to own, one of the key ingredients to having a happy and long-lived Betta fish is getting the right Betta fish heater.  These are designed to manage the temperature of the water and keep it consistent and comfortable for the little guy and let them enjoy their aquatic existence in luxury and comfort.  Bettas are tropical fish and are therefore used to warmer waters and while small tanks are perfect for a Betta, the smaller the tank the more susceptible to air temperature the water becomes, and Bettas like it in the high 70’s to low 80’s.  Which means in most houses, they’ll need a heater.

The top heater for any 5 to 10 gallon tanks is the Fluval Marina Mini, which is submersible, easy to install as it comes with brackets and suction cups and is relatively compact being only six inches long.  The heater is designed to be fully adjustable and incredibly accurate in controlling temperature fluctuations. It comes in two different wattage models for various tank sizes with a smaller 25-Watt model designed for the 5 gallons and under tanks and a larger 50-Watt heater that can handle up to 10 gallons of water.

The Tetra HT10 is another fantastic Betta heater, designed for a 5 gallon tank it is preset to heat the water to 78 degrees, so it has a simple set it and drop it design.  There are LED lights that indicate the status of the tank, if the light is red then the water is heating and if the light is green then the water is currently at the correct temperature.  The simple set it and forget style of usage is fantastic for the submersible heater as it will work in up to 5 gallons of water.

The ViaAqua 50W Heater is another great choice for a Betta heater, as it comes with a lot of the features that are usually reserved for more expensive models but the easy to install and durable device is relatively inexpensive and able to work on up to 13 gallons of water.  Its submersible, has a fully adjustable temperature setting and comes equipped with suction cups to enable easy install as well as being made from quartz-glass making it highly durable. This tough, elegant heater can even be used in some slightly larger tanks than just a Betta tank making this a possible investment for the aquarium enthusiast who seems themselves staying small but maybe upgrading from a single Betta.

Another great option is the Zacro 50W Heater.  Designed for tanks up to 15 gallons or larger, it has automatically controlled temperature and an 18 month warranty to protect the added expense.  The simple submersible design of this heater has suction cups or it can be laid down at the bottom of the tank. It has a simple dial at the top with a digital read out on the wand, letting you know what temperature you have set the heater to, and is well designed from durable plastics protecting the fish from the heating element itself.

The simplest which in some ways is the best option is the simple but elegant Marina Betta Heater.  Designed for up to three gallons of water, the non adjustable, submersible little heater is the perfect option for setting and dropping the 8W device in the tank and forgetting it.  The heater is designed to automatically heat and maintain the designated temperature, making it an east and excellent choice for the small, single Betta tanks so many people keep as decoration around their house.

While owning a Betta is fun and a simple starter pet for many people who are getting adjusted to the pet owning life, there are some necessities.  Obviously there’s changing the water consistently to keep the fish healthy and disease free, there’s feeding it so the fish doesn’t starve to death and then just as important for a happy and healthy fish is there water temperature.  Keeping a warm water fish happy for most people requires a lot of work, warm air temperature or a heater. Going the heater route is usually the best alternative and one way to figure out which heater best fits a certain setting is to check out guides like this one.  Novice tank builders should of course always ask for guidance from an expert but ultimately owners should do whatever makes them and the fish, happy.

 

Best Aquarium Filters

Owning an aquarium is a fun and relaxing endeavor most of the time, obviously the regular cleanings are the exception, and the thing that makes it possible to relax and enjoy an in-home aquarium is the filter.  The purpose of a filter in an aquarium is to ensure there is enough oxygen in the water for fish to be able to breathe as they hang out in their manufactured aquatic wonderlands. There are several types of filters from an internal filter, to a canister filter to a hanging on the back filter there are good filters and bad filters, these are the best filters.

A canister filter is usually much larger than a hang on the back filter and actually pulls the water out of the tank through a sieve or tube of some kind and into a large filter media that cleans the water before pouring the water back into the tank by a stream or waterfall of some kind.  The top canister filter is the Fluval FX6. While it’s massive filter media capacity and ability to service up to a 400 gallon tank means it isn’t ideal for small aquariums, it’s ideal for any medium and up size tank. Equipped with a three year warranty, this energy efficient and simple to start self-priming filter is the top of the canister category.  

If you have a smaller tank and are looking for a hang on the back filter, so called because they literally hang on the back of the aquarium and are also called power filters, then you’re looking for a Marineland Emporer 400 Power Filter.  Able to effectively filter tanks up to 80 gallons of water, the extremely efficient biological filtration system is designed to be incredibly quiet while running and can accommodate up to four filter media types. The adjustable flow rate is a great feature on the smaller and simpler device than the Fluval, giving Aquarium enthusiasts a smaller option for their tanks.

For those who are enjoying an even smaller tank and are therefore looking for an internal filter, the best option is the Aqueon Quietflow 30.  Internal filters are designed to function inside the tank and therefore it allows your smaller tanks to be able to be placed flush against the wall however even the top of the line filter like Aqueon Quietflow 30 can only handle 30 gallons of water.  This quiet filter can function in as little as two inches of water and is designed to be placed discreetly inside the tank making it a convenient choice for the small tank enthusiast.

For those who aren’t sure or are looking for other brands there are a few runner ups in each category.  In the Canister style, there’s the Marineland Magniflow canister, Cascade CCF3UL canister, the SunSun HW-302 Canister, the Fluval 406 Canister, the Eheim Classic Canister, the API Filstar XP-L Canister, Hydor Canister, and the Eheim Pro 4+ Canister filter.  In the Hang on Back or Power filter category the Aquaclear 70 Power filter, the Fluval C4 Power Filter and the Tetra Whisper Power Filter are all excellent options. If someone is looking for another internal filter option the Rio 90 Mini is another solid choice in that category.  

Each filter type has is its own pros and cons, and are limited by the size of the aquarium in question, the more water that is needed to be filtered the more likely it is that it will require a canister filter.  With the best power or hang on back filter’s able to handle up to 80 gallons of water meaning much more water than that and you will need to be in the canister category. While Canister filters are the best of the three types for both mechanical and chemical filtering and are designed for larger fish and saltwater, the larger size also limits where a tank can be placed in regards to a home and also the price tag, with canister filters usually being more expensive than their smaller counterparts.  The hang on back or power filters provide awesome filtration partly because over time within the filter media good bacteria begins to build up during the filtration process making the filter more efficient, however whenever it’s time to clean and swap out the filter media those good bacteria colonies are obviously lost and have to regrow in the new media during use. Another common complaint about power filters, although it has improved over recent years, is the noise, they are known as the loudest of the filter types.  For those with an even a smaller tank, the better option is the Internal filters because they are designed to produce oxygen bubbles with their air pumps and air hoses that benefit a small tank, something to remember is the smaller the tank the faster the toxins build up in the water and while internal filters are great they only are recommended for the smallest of tanks.

There are other filtration options, such as a sponge filter designed for even smaller beta fish displays and things of that nature, of those the Hydro Sponge Pro Filter is the number one pick.  The complicated and rarely recommended undergravel filtration systems, of which the Penn-Plax Premium Undergravel filter is the leading choice.  

Obviously there are tons of choices for filters for an aquarium enthusiast to choose from, deciding which one is determined by a couple of things.  Filters are required to remove the solid and organic waste as well as any biological waste from the water as it pulls it through a series of filtration media, or as it flows through, depending on its design.  Ultimately though the leading factor in deciding what type of filter that should be used in any tank is the capacity of the tank for holding water and how much maintenance the owner is willing to do. If someone isn’t sure or is new to the aquarium experience research and help are recommended in setting up a first tank, however ultimately its up to the tank owner to decide what system is going to work best for them.

How much do the Tanked aquariums cost?

Tanked is a popular and awesome tv show, where large aquariums are built for some pretty interesting purposes. The tanks on the show aren’t just large though, usually they’re very large and completely custom builds. So when people are watching the show, often they wonder how much one of those tanks will cost.

The guys who produce the tanks from the show Tanked have their own website, but they don’t actually list prices on there – because every aquarium build they do is custom. However, it’s likely that due to their popularity they don’t work with clients for the show Tanked unless they’re willing to spend in excess of 5 figures for an aquarium ($10,000+).

So that’s how much an aquarium from Tanked costs! If you’re in the market for a large custom aquarium then we can build those too, feel free to get in touch with us today. 

Best fish for a bowl without a filter (3 options)

Typically a fish bowl without a filter is thought to only be suitable for snails, shrimps and other small creatures like that, rather than fish. But did you know that there are actually a number of types of fish that can live in a bowl without a filter perfectly comfortably? It’s true!

We decided to create this guide outlining all of the fish that can live in a bowl without a filter, so if you’re a beginner or you just want to add a bowl to your collection, you know what fish to use. Generally, it’s the more resilient types of fish who are best suited to living in a bowl without a filter – the types of fish who are not as susceptible to infections and can live in a wide range of environments due to their ability to adapt to different water parameters (known commonly as hardy fish).  Because bowls don’t have a filter, you often need to change the water daily to ensure the health and happiness of your fish. But by choosing hardy fish, you’ll reduce the risk of them getting ill or worse, dying in the bowl. Equally, you’ll want to go for smaller fish (that’s very obvious) but also cold water fish, as it’s difficult to attach a heater to a bowl so you’ll want fish that are comfortable in colder water. Let’s look at some types of hardy fish that would be ideal for a bowl without a filter:

Guppies

Guppies are really easy to care for, and can comfortably live in a bowl without any need for filtration equipment. They’re small, coldwater and will very happily live with other guppies. If you have a small bowl (say 2 gallons), then the general rule of thumb would be 1 guppy per gallon.

Betta Fish

Betta fish are comfortable in smaller fish, but keep in mind that they can’t be kept together otherwise they will definitely start fighting!

Zebra Danios

This is a popular type of fish for beginners as they are very easy to care for and can easily remain healthy and happy in a bowl. They’re a freshwater fish so can live comfortably without heaters.

 

Hopefully this guide helps you decide what fish would be a good choice for a fish bowl without a filter. We’d always recommend that you choose a tank over a bowl, but if you’re a beginner then getting started with a bowl can be a great decision.

 

Best fish for 10 gallon tank

Stocking a 10 gallon aquarium can actually be quite difficult – you’ve got an awkward amount of space to fill, and you need to make sure that you’re choosing fish that will live well together. It’s not a huge amount of space either, so you’ll need to think about the size of the fish you’ll be putting in the tank, and how much room the fish will have in the tank to ensure that they’re healthy and happy.

With this guide, we want to help you figure out how you should stock your 10 gallon aquarium – we’ll be giving you advice on how many fish you should have, what types of fish and what fish are best for a tank of this size.

So let’s start with the most difficult question….

How many fish can you keep in a 10 gallon aquarium?

There is no straightforward answer here – it really depends on the type of fish you want to have, and what size they are. Our recommendation is to plan this very carefully. Don’t just think about what size your fish are now, think about what size they’ll be once they’re fully grown, and measure your 10 gallon tank carefully to ensure that your fish will still be able to live in it comfortably once they’re at their full size.

You should also think about how dirty the tank will be if you have more fish in it. So although you might be able to fit around 20 small fish in a 10 gallon aquarium, that will mean a lot of work in keeping the tank clean and it will also mean you won’t have as much room for fun things like plants and aquariums!

What are the best fish for a 10 gallon tank?

Ideally you’d want to choose smaller fish for a 10 gal – the main reason for this is that it’s not a huge amount of space in a tank like this, so the smaller the fish you choose, the more you can put into your tank. There are some obvious fish that you might want to include in the tank – a Betta fish, Tetras or Guppies are all ideal choices. However if you want some more interesting types of fish in your tank, you could easily add in some Corydoras, Sparkling Gourami or Killifish.

Hopefully this guide helps you choose the best fish when you’re stocking a 10 gallon aquarium!

 

The best fish for a 5 gallon tank

A 5 gallon aquarium is one of the more popular sizes that you’ll see in homes. It might not be a huge amount of space, but there is enough room to stock some pretty fantastic varieties of fish. The most important thing here is to ensure that the fish you’re stocking will have enough room to be healthy and happy, otherwise they’ll be at risk of infection or even worse, death.

So when choosing what fish to stick in a 5 gallon fish tank, it’s crucial that you choose wisely. That’s why we wanted to outline the best fish to include in a tank this size, and how many fish you should have in a 5 gallon aquarium. Before we get started with the list of fish options, let’s figure out how many fish we can have in a tank of this size.

How many fish can you put in a 5 gallon tank?

There is no one size fits all answer here (please excuse the pun). When considering how many fish you’ll put in your aquarium, you’ll have to think about the size that your fish will be when it’s fully grown, and whether or not it will still be able to live comfortably in 5 gallons. You could always move the fish to a larger tank once they start growing in size, but a good general rule of thumb would be to consider what size the fish in your tank will be when they’re fully grown, and if they wouldn’t still fit comfortably in the tank then either get a larger aquarium or get some smaller fish!

 

What are the best fish for a 5 gallon tank?

Now we’re getting to the fun bit! Deciding on what fish to put in your tank is where the real enjoyment is, and although 5 gallons is pretty small you should be able to have some pretty tropical and interesting fish in your tank. For example, the most obvious type of fish to have in a tank of this size would be Betta fish, as they’re small and colorful. But there are some other types of fish you might like to consider for a tank of this size:

  • White Cloud Moutain Minnow
  • Honey Gourami
  • Clown Killifish
  • Least Killifish
  • Various Micro Rasboras
  • Dwarf Puffer

If you wanted to combine some of these fish alongside some plants or ornaments, then there are a few different variations you could go for. Killifish are probably best kept with other Killifish only, but Bettas are good with most types of fish, and all of the fish we listed above wouldn’t mind a few ferns or moss balls in the tank for some extra plant life.

So that is our guide for stocking fish in a 5 gallon tank. hopefully you have enough information to get started!

Python Water Changer (An Honest Review)

Until you discover the Python Water Changer, people are usually changing aquarium water every week the same old fashioned way everyone else does – with a bucket and a siphon.  This long, frustrating process is perhaps the biggest annoyance to having a nice, large aquarium because of the sheer amount of time and work that is required

But now with a Python Water Change System, people are able to do the job in around thirty minutes without dealing with most of the mess everyone usually has to deal with.  The Python Water Change System makes the entire process a much simpler one than the old way, utilizing a simple mechanism to both clean and refill the tank easily and quickly. 

 

image of python water changer

Lance Reyniers created the No Spill, Clean and Fill System that is the Python Water Change System and possibly changed the level of convenience for aquarium cleaning around 30 years ago.  Based in Milwaukee, Python Products sells around the world and is available on the Petco website and of course Amazon. They arrive with no assembly required and able to connect to most faucets straight out of the box.  Affordable and able to arrive at your house in the span of a few days, Lance’s product is the king of convenience in aquarium cleaning.

How to use the Python Water Changer

The simple device works by attaching the T-Pump to the faucet and then turning on the water to create the suction necessary to pull the water up the apparatus.  Then you simply drag the gravel tube through the bottom of the tank to clean out the bottom dirt in the tank and then once the water level is low enough, swap out the gravel tube for the small water hook that is easily purchased separately.  Then reverse the flow of the water on the T Pump and suddenly the same device that was draining the water is now refilling the tank. Finishing what was once a complicated and manually intense process in a simple, timely manner. Eliminating what was once a long and physical draining process.  Prior to having the Python Water Change System, you have to physical scoop water out of the tank and then scoop out the gravel from the tank, clean it, put it back and then slowly pour new water into the tank.

While the water change system doesn’t work with all faucets and you can’t disconnect it from the sink during the draining but beyond those minor inconveniences the system is compact, easy to store, easy to set up and even easier to use.  While there are a few extra pieces that buying does make the process even easier, if you decide not to, it’s still an easy process to change the water. Much easier than the old method of manually draining the tank and hand cleaning the rocks.

 

What extras come with the Python Water Changer?

When the Python Water Change System arrives at your house, it comes equipped with almost fifty feet of hose to give you some range as to how close the aquarium in question has to be to the faucet in question.  The durable, clear plastic Gravel Tube that comes with the unit is one of the smaller ones, so buying one of the larger ones is probably a great idea to increase the ease with which a tank is cleaned although the size of the tank will ultimately determine the minimum length you need.  It also comes with a Faucet Adapter that fits to most sinks, but be aware it doesn’t connect to all faucets as there are some that it just won’t fit, so on this point a little bit of research is required. There’s a faucet pump in the box, which is designed to allow you to change the direction of the water with a simple flick of the switch, making it an ease to move the water in and out of the aquarium.  In addition to the pump there’s a switch that attaches to the Gravel Tube that allows it to alternate between draining the tank and filling it. The one piece that isn’t included that greatly increases the ease of the cleaning and swapping of the water is The Hook System which is sold separately. If you purchase the hook system and the larger gravel tube, the Python Water Change System becomes the time saving, convenient and easy way to clean aquariums, large and small.

So, do we recommend the Python Water Changer?

Absolutely! Overall, the ease and convenience that comes with such a simple method of changing and cleaning an aquarium that comes in the Python Water Change System makes it an amazing value.  Saving both time and physical labor only adds to the overall value. Rather than lugging heavy buckets of water into and out of the house and then having to hand clean the gravel on the bottom, you simply install the T Pump to the faucet and run the hose to the aquarium and from there it gets even easier with The Hook System.  After cleaning the tank with the Gravel Tube and draining the water to the desired level, you simply swap the tube out for the Hook, leave the Hook on the side of the tank and reverse the flow of the water and wait.

Before you guys go rushing out to get a wall mounted fish tank or aquarium, there are a few things that you should be aware of:

Firstly, make sure that the wall that you’ll be mounting the tank or aquarium on is actually sturdy enough to support the weight. Although most of the fish tanks included in this list aren’t too large or heavy, there’s always a chance that your wall might struggle with the weight. Add on top of that the several gallons of water you’ll be adding to the aquarium, and you’re basically putting a big weight on your wall! So it’s absolutely essential that the wall is strong.

You’ll also want to make sure that you have the proper mounting hardware for your fish tank or aquarium. This will usually come with the tank (and has been specified above if it has been included).

Finally, generally speaking fish tanks and aquariums that you mount on walls tend to be smaller, to try and make them lighter. This means that you might not be able to fit larger species of fish in a wall mounted fish tank, so they’ll generally be better suited for smaller fish like Bettas.

Now for the positives! Having a fish tank mounted on your wall can save you huge amounts of space. Although fish are small creatures, the space that they require can be much bigger than you’d expect. By keeping your aquarium on the wall, you’ll save lots of valuable space. You’ll also keep your beloved fishy friends out of reach of people (or pets!) who could potentially knock their tank over.

Now let’s get into the guide:

Brushed Aluminium Fish Bubble

Wall Mounted Acrylic Fish Bowl

Prugna Wall Fish Bowl

This is a surprisingly highly rated product over on Amazon – I say surprisingly, because admittedly very few of these wall mounted fish tanks tend to be very good, and the bowls tend to be even worse. They’re usually poorly made and not safe, but based on the reviews over on Amazon, it’s say to safe that this wall fish bowl from Prugna is actually pretty awesome.

Here is a quick rundown of the fish bowl:

  • 1 gallon – Only suited to smaller fish

10 Gallon Fish Tanks & Aquariums (Kits & Stands)

Our collection of 10 gallon fish tanks and aquariums is one of the most comprehensive (and varied) on the internet. We've searched the web to bring you the very best collection of 10 gal tanks out there, both glass and aquarium, and we've also included a variety of different designs and features, as well as kits (which are perfect for beginners) and stands (which are perfect if you want to show your fish off). It's important to note that these aquariums aren't exactly massive - in fact, we'd only recommend this size of aquarium for very small fish. Here is a quick overview of the best 10 gallon aquariums we've included in our guide:

And here are the more detailed reviews:

What are the best fish for a 10 gallon fish tank?

We actually have a full guide about this linked above, but as a summary - there is not a huge amount of space in a 10 gallon tank, so you need to make sure that you choose your fish wisely. Generally the best fish for an aquarium of this size are fish like Danios, Tetras and Guppies. I would go as far as saying that any peaceful fish between 1-2 inches in length would be suitable for a tank of this size. You could keep 3-4 fish in the tank at this size. If you're wanting more fish, I'd recommend a 30 gallon or 20 gallon. 

What equipment is needed and what is the best setup?

For most 10 gallon tanks, you'll need a filter, heater and lights. Most tanks in this list are starter kits, so they come complete with quite a lot of this equipment. If you're a beginner and you're still learning about keeping fish, then I'd suggest getting a starter kit.

Aqueon 10 Gallon Fish Tank Starter Kit (less than $90)

Aqueon are a brand that we feature pretty regularly on FishTankBank, and for good reason – they’re a reliable company who make great looking and functioning fish tanks. This 10 gallon aquarium starter kit is proof of that – equipped with everything that a beginner would need to get started on their fish keeping adventure, it’s a great purchase for anyone who needs an ‘all-in-one’ solution to help them get started with their fish. The filter that this fish tank comes with includes an ‘indicator light’ that is a clever little feature which lets you know when the cartridge needs changed (so you don’t have to check yourself). We’ve got a slightly larger 30 gallon Aqueon aquarium here. The kit includes:

  • Currently priced at less than $90
  • Made from glass LED lighting system (including LED hood)
  • 50W heater Fish food & net Thermometer
  • Dimensions – 20.2 inches x 10.5 inches x 13.3 inches
  • Over 50 reviews on Amazon (with an average of 4 stars)

Marineland BioWheel Kit

A BioWheel is a unit that provides biological filtration, which can be a really helpful (and in many instances crucial) addition to have in a fish tank, as in this Marineland aquarium. It’s not just a BioWheel that makes this tank an awesome choice – it’s got plenty of other nifty little features that make this tank a firm favorite of ours at FishTankBank, however it’s the Penguin 75 bio-wheel filter that is the real standout feature here. It rotates as it’s running, which increases aeration and the production of healthy bacteria in the water (always helpful). Other features include:

  • LED lighting system
  • Stylized hood that creates a shimmering effect in the water (mimicking water in the natural habitat of your fish) and reduces evaporation
  • Submersible 50 W aquarium heater
  • Made from glass
  • Tropical fish flake food
  • Dimensions – 12 inches x 20 inches x 12 inches

Clear-For-Life Aquarium

Clear-For-Life have a great range of simple fish tanks that provide the safety and comfort that your fish needs to make them happy! These Clear-For-Life aquariums have a lifetime warranty associated with them, which is perfect. We’ve got a nice much larger version of this tank over on our 100 gallon fish tank page. Other notable features of this awesome tank include: Made from highest quality acrylic – stronger, lighter and clearer than glass Available in 3 colors – colored back panel also available Suitable for freshwater and saltwater Rectangular shape Dimensions – 20 inches x 10 inches x 12 inches

Top Fin 10 Gallon Fish Tank (Hooded)

Compared to the rest of the fish tanks included in this countdown, this hooded aquarium from Top Fin is seriously cheap. At only $30, it’s an absolute steal. What’s even better about this tank is that it has some awesome reviews, with an average score of 4.4 stars out of 5 from 50 reviews. There’s even a video that demonstrates how to to use this tank efficiently! It’s almost identical to the Top Fin tank that kicks off our 20 gallon fish tank page. The main features of the tank include: Made from glass fitted with center-braced framing to prevent bowing Fluorescent hood Available in the color black Rectangular shape Dimensions – 10 inches x 20 inches x 19 inches

All Glass Aquarium/Eco Hood

I have a confession to make – I’d never heard of All Glass Aquariums before starting my reviews for this list. But it got my attention because of all the positive reviews it had (from over 30 reviewers), so I decided to explore a bit further. The most interesting aspect of this All Glass aquarium is that it is economical – something that very few other fish tanks can claim to be. The ‘eco hood’ is essentially a low profile LED hood that won’t eat away at your energy bills. You’ll also get:

  • Currently priced at less than $75
  • Made from glass
  • Eco hood
  • Dimensions – 20.2 inches x 10.4 inches x 12.6 inches

Tetra Half Moon Aquarium Kit

Tetra are big fans of the half moon shape for their fish tanks and aquariums, and so are we. They allow for a great view of your fish while also providing your fishy friend with the chance to get some much needed privacy and quiet (if they want it). You’ll also be able to brag to your friends that your fish lives on the ‘light side of the moon’. The unique shape means it is a little bit taller than your average tank, making more room for taller plant decorations (if that’s what you fancy). Before you get this tank you should be aware that the lid has quite large holes in it, which smaller fish could potentially jump out of if you aren’t careful. In theory you could simply lower the water levels slightly to prevent this from happening. There are a few other features of this 10 gallon tank that we love, including: Frameless top – so you can enjoy the view of your fish without obstruction Cartridge filtration Whisper filtration – keeps water clean and safe 50W heater Dimensions – 18.5 inches x 12.6 inches x 20.8 inches An average of 4 stars from 90 reviews on Amazon

Aqua Culture 10 Gal

There’s not much to say about this fish tank – it’s completely empty! Think of it as blank canvas for you to create the perfect environment for your fishy friend. It’s designed for fish, but could even be used for reptiles as it’s made from strong glass making it very versatile. Other notable features include:

  • Currently priced at less than $30
  • Glass enclosure
  • Silicone casing – high strength
  • Dimensions – 20.25 inches x 10.5 inches x 12.63 inches

Marina LED Aquarium Kit

Unlike most other brands included in this countdown, Marina haven’t actually been included very often on FishTankBank. But that doesn’t necessarily make them a poor choice – they might not have a huge amount of products available, but what they do sell tends to be really good. This 10 gallon LED aquarium kit is a good example of that (and the reviewers on Amazon seem to agree – over 170 reviews and an average score of 4 and a half stars!). The main features of this tank include: Made from glass Daylight effect LED lighting Clip-on filter Fish net (soft mesh) & food Aquarium care guide Dimensions – 22.6 inches x 12.6 inches x 15.3 inches

Aqua Culture 10 gallon Aquarium Starter Kit

Aqua Culture have tried to create an ‘all in one’ starter kit for anyone who wants the ultimate 10 gallon tank. It has an average rating of 4 stars on Amazon so they must be doing something right. The real benefit of this starter kit comes from the fact that it includes pretty much most things that you’d need to get started, including: Charcoal pump filter LED cover Made from glass Fish food Set up booklet

Innovative Marine 10 Gallon NUVO Fusion

We don’t feature fish tanks from Innovative Marine on our site very often, which is a shame really as they make some seriously interesting and cool aquariums, like this 10 gallon variety of their Nano Fusion tank. Aside from looking cool, the tank has a bunch of useful features that make it a great choice for beginner and intermediate fish keepers, including: High clarity low iron glass, built in overflows, filter sock.

Oceanic Systems Black Fish Tank

This is a very basic fish tank that has mixed reviews over on Amazon. The general consensus seems to be that it’s cheap, and it kind of feels that way. Regardless, we decided to include it purely to give a different perspective in this list, and it does have some pretty decent reviews from people who knew what they were getting for their money. The main features of the aquarium include: Made from glass Dimensions – 26 inches x 26 inches x 14 inches

Penn Plax Curved Glass 10 Gallon Aquarium Kit

This Curved aquarium from Penn Plax is available in a few different sizes, but we’ve included the 10 gallon variety in this post (makes sense right). It’s a pretty awesome looking fish tank and has some genuinely useful features that make it one of the best choices in our list. The glass is described as ‘bent’, which although admittedly might not sound like a positive thing, it essentially described the curved shape of the glass which gives it such a unique look. Other cool features of this fish tank include:

  • Currently priced at less than $82
  • Frameless and seamless front for non-obtrusive viewing of your fish
  • Internal filter
  • LED lighting system
  • Dimensions – 17 inches x 11 inches x 12 inches
  • Average score 0f 4 stars from over 40 Amazon reviews

Less than 10 Gallon Fish Tanks

 

Fluval 9 Gallon

This 9 gallon fish tank kit isn’t just designed to keep your fish safe and happy, it’s also designed to support the growth of plants. It has a powerful 7500k LED system which will ensure the plants stay healthy and continue to grow long after you’ve placed them in the tank (and the system comes with a remote control). The aquarium also has a bent glass design similar to other tanks in this list, providing a unique viewing experience and creates the illusion that everything inside the tank is larger than it actually is (so don’t be alarmed if your friends think you’ve got a shark in your tank). A nice feature of this tank is that the lid is very simple to remove, despite the complicated design. The filtration system is in the back of the tank, and has plenty of room for a considerable amount of filter media.

Fluval Edge Aquarium

This is actually a 12 gallon fish tank, but there’s no harm in including it in this 10 gallon list (unless you’re deeply offended, in which case I apologize profusely). It’s another tank from Fluval, which is why it has such a unique design, which includes 6 sides and a vent under the lid that makes the tank appear to have no air at the top. The glass lid reduces evaporation, but there is still a filter in then lid to ensure oxygen exchange. 3 stage filtration is included, ensuring that the water stays clean and healthy. Plus you get a nice LED lighting system and it’s available in 3 colors – silver, black or white. Dimensions are 14 inches x 17 inches x 22 inches

Aqueon 10 Gallon Fish Tank (Black)

This is another Aqueon 10 gallon aquarium, this time from PetCo. It has black rims and is currently on offer over on PetCo. The reviews for the tank are overwhelmingly positive, with many Betta fish owners saying that their Betta really loves the tank. If you’d like to learn more about this product, please feel free to visit PetCo through the link below.

Fluval Edge Aquarium

This is another Fluval Edge aquarium, and again it’s available through PetCo. The product has an average rating of 4 stars from more than 40 reviews, which is very high. One of the coolest features of this tank is it’s 3 position switch, which allows you to choose between different lighting settings – bright daytime, deep blue nighttime and completely off. It also comes with handy features like low voltage power (to save energy) and 3 stage filtration. It’s ideal for the home or even the office, check it out below.

Aqueon Aqua Springs Kit

This 10 gallon aquarium from Aqueon has 2 purposes – to look great and to provide a comfortable environment for your fish. Made with high quality glass and fitted with QuietFlow filtration, it’s attractive enough and subdued enough to sit within a bedroom or an office. The tank is fitted with concealed LED lights which add to the calm and collected feel of the tank, hopefully keeping you (and your fish) really chilled out!

Aqueon Ascent 10 Gallon Aquarium

Aside from having a really cool name (‘Ascent’ makes it sound otherworldly), this is a seriously cool fish tank. Firstly it’s completely rimless, so you can see every inch of your 10 gallon space, plus it makes viewing your fish much easier. Plus this is a kit, so you get a whole bunch of things with your purchase, include:

  • LED lighting
  • Floating base
  • QuietFlow Power filtration
  • Filter cartridge
  • Premium fish food
  • Set up guide

Biorb by Oase (Classic)

This fish bowl from BiOrb has a unique look, but still does everything you need it to. It’ll keep your fish happy, and it’ll look great wherever you put it. The main features include:

  • Made with acrylic – stronger and lighter than glass
  • 5 stage filtration system
  • Low power voltage – 12V
  • Equipped with low voltage LED lighting
  • Includes filter cartridge
  • 4 star rating from more than 30 reviews

Stands

Caitec 10 Gallon Fish Tank Stand

This stand is specifically designed for fish tanks which are roughly 10 gallons in size and weight, so it’s perfect for any of the tanks we’ve included in this list. The main features of this tank are:

  • Dimensions: 22-1/2 inches length x 31 inches high x 10-1/2 inches wide
  • Average rating of 4 stars out of 5 from over 30 reviews
  • Powder coated (rust and water damage resistant)

How many fish could I put in my 10 gallon tank?

Generally, the rule of thumb with fish tanks is 1 inch of fish per gallon of tank, so with only 10 gallons there isn't masses of room for fish here. Ensure that you're leaving plenty of room for your fish to be happy and healthy. The best fish for a tank with these dimensions would be a guppy or a betta or something similar.
