5 Gallon Fish Tanks & Aquariums (Kits & more)


A 5 gallon aquarium is a great size for most homes and is small enough to fit comfortably in a room without taking up too much space. It’s also an adequate volume for a good amount of smaller fish, as well as a few plants and ornaments if you want to add some style to the tank. Before we get into the more detailed guide, here is a quick overview of the highest rated tanks we included:

5 gal Tetra aquarium

Tetra Crescent 5 Gallon Fish Tank Kit (Acrylic, less than $50)

We decided to kick off our list with this awesome 5 gallon aquarium from Tetra because it has a very impressive 4 star rating from over 210 reviews. When you take a look at the tank, it isn’t hard to see why. It’s probably easier if I just list the features:

  • Currently less than $50
  • Energy efficient LED lighting
  • Made from acrylic
  • Curved to provide a unique viewing experience
  • Whisper internal filtration
  • Dimensions – 17 inches x 11 inches x 13 inches
5 gallon marina aquarium

Marina LED Aquarium Kit

Although this tank is also available in a 10 gallon and 20 gallon variety, we’re obviously going to be talking about the 5 gallon version in this post. Unfortunately we’ve only got a picture of the box to show (it’s a nice looking box I suppose), but if you read some of the reviews there are people who’ve posted pictures of their tanks that you can check out. Other notable features of this aquarium includes:

  • Currently available for less than $70
  • Made from glass
  • 4 and a half star rating from over 190 reviews
  • Clip-on filter
  • LED lighting fixture
  • Fish net & food
  • Set up/care guide

Marina 5 gallon LED fish tank

Marina LED 5 Gallon Fish Tank Kit

This cute little 5 gallon tank from Top Fin has a really unique design that we’ve absolutely fallen head over heels for. It might look like it has some kind of weird quiff going on, but that’s actually a nifty little LED feature that really sets this tank apart from most other tanks of a similar size. Other noteworthy features of this aquarium include:

  • Currently available for less than $70
  • Built in filtration – keeps the water clean and healthy
  • Made from glass
  • LED light feature
  • 14 inches x 9.5 inches x 9.5 inches
  • Average score of 4 stars from over 65 reviews
Koller 5 gallon aquarium

Kollercraft Aquarium

This tank is from Kollercraft, one of the best fish tank companies currently out there. At 5 gallons, this is probably what I would describe as an ideal betta fish tank, because it has enough room to comfortably hold a couple of Bettas (so would a 3 gallon tank). Here are the main features of this awesome Betta aquarium:

  • Currently available for less than $35
  • Power filter – makes it incredibly easy to keep the tank clean and keep your Bettas healthy
  • LED lighting – brings out the beauty of your Betta
  • Flat backed with rounded front – creates a unique shape
  • Acrylic – provides a crystal clear view of your fish
A portrait fish tank

Marineland Portrait Aquarium

This is described as a ‘portrait aquarium’, which essentially means it was designed to show off your fish – that’s exactly what we think it’s perfect for Betta fish, arguably the most attractive species of fish out there. At 5 gallons, it’s pretty much the perfect size fish tank for a Betta fish, and it also comes with a few other extras:

  • Currently available for less than $75
  • Hidden back panel filtration – keeps the tank clean and your Betta healthy without taking up too much space
  • Bright white & blue LED lighting
  • Sliding glass canopy – makes it easy to admire your Betta fish
  • 4.5 star rating on Amazon from 400 reviews – wow.
A Fluval edge aquarium

Fluval Chi Aquarium (5 Gallons)

Although this fish tank isn’t actually designed specifically for Betta fish, it’s simply a well built aquarium that is perfect for smaller species of fish. It’s a fairly plain tank, which isn’t full of unnecessary features that will get in the way of your Betta. The one feature that this tank does include is a small ‘garden’ in the middle of the aquarium, providing your Betta with the cover and privacy that they so often crave. This aquarium includes:

  • Base stand
  • Low voltage LED lighting system (consisting of 17 lights)
  •  Filter media
  • Water conditioner
a 5 gallon Marineland aquarium

Marineland 5 Gallon Betta Escape Hexagon Aquarium

Despite having a name that makes it sound like some kind of theme park ride which is a hybrid of a haunted house and a log flume, the Marineland Escape is an excellent choice if you’re looking for a fish tank for your Betta fish. The main selling point of this aquarium is the ‘multiple hex-shaped viewing panels’ (their words not ours) which allow for 360 viewing of your Betta. You’ll also get:

  • LED hood
  • hidden filtration system
  • Adjustable flow pump
  • Made from plastic
Top Fin Aquaponics aquarium for desk

Top Fin Aquaponics 5 Gallon Desk Aquarium

This 5 gallon desk aquarium from Top Fin is quite similar in style to the first tank in this list, mainly because of the LED light feature that you see over the top of the tank. The fish tank has just about everything you need to get started (aside from fish), including:

  • Planter lid
  • Integrated filter
  • LED fixture – helps to grow plants
  • Dimensions – 14 inches x 10 inches x 10 inches
a 5 gallon imaginarium

Imagitarium 5 Gallon Freshwater Aquarium

Calling this fish tank the ‘Imagitarium’ makes it sound like something from Willy Wonka rather than a vessel for your beloved fishy friend, but trust us this is a totally awesome 5 gallon aquarium! This is described as a desktop tank, which essentially means it’s perfect for sitting on a desk. It’s made with acrylic, which is stronger and lighter than glass. Other notable features of this tank include:

  • Blue/white LED lighting with day/night settings
  • Internal filtration system
  • Easy access lid
  • 9.7 inches x 16.5 x 12.5

Aqueon MiniBow Aquarium Kit

Another Aqueon product in this list (we’re pretty used to their name around here) and another desktop aquarium. What makes this tank even more perfect for sitting on a work desk is that it is fitted with QuietFlow filtration, making it very quiet. Other notable features of this 5 gal beauty include:

  • Filter and pump included
  • LED lighting system
  • Water conditioner
  • Fish food sample
  • Easy cleaning

Fluval Spec V Desktop Aquarium Kit

This is a pretty stylish 5 gallon aquarium kit from Fluval, which includes just about everything you’d need to get started. We may as well just list it all as there is so much included! Here you go:

  • Adjustable pump
  • Filter with carbon/biological inserts
  • LED lamps
  • 3 stage filtration system
An aqua culture 5 gal tank

Aqua Culture Aquarium Starter Kit (5 gallons)

How nice to round off this epic list (surely the most epic on the internet) with a cute little aquarium starter kit, perfect for beginners. This tank would be perfect for a kid who is just getting started with their fishkeeping adventures, and who wants to have a little tank in their room. Cool features of this aquarium include:

  • Long life LED lighting system
  • Food sample
  • Internal filter

5 Gallon Fish Tanks FAQ

Our list of 5 gallon fish tanks and aquariums features a few tanks that you might recognize from our ‘Betta‘ page, as well as some other high end items that you won’t find anywhere else on the site. We think that 5 gallons is a great size for a smaller fish and if you have the space for a tank of this size, you should absolutely go for it.

Are these best for Betta fish?

Yes, 5 gallons is probably big enough for a Betta fish. However you should still ensure that you follow the general rule of thumb for all fish tanks (1 inch of fish per gallon of aquarium).

How many fish could you fit in a 5 gallon tank?

Again, it depends on the type and size of the fish. See our answer above for the rule that you should always use when deciding whether or not your tank will be suitable for your fish.


3 Gallon Fish Tanks & Aquariums (Kits & more)


A 3 gallon aquarium is a great size for anyone getting started with fish keeping, as it can hold a comfortable number of fish and can fit easily in most homes. It also leaves a little room for some plants and decorations, allowing you to add a little style to the tank too. Before we get into our full guide about 3 gallon aquariums, here is a quick overview of what the best tanks included in the guide are:

And now for the full detailed guide:

Marineland 3 Gallon Nook Aquarium

Another Marineland aquarium, another funny name (Nook? Seriously?). What this fish tank lacks in name, it more than makes up for in functionality, design and ‘badassery’. Your fish will be having the time of his life in here, plus you’ll have room for decorations and ornaments if you like. Along with the fish tank, you’ll also get:

  • LED lighting system
  • Hidden filtration system
  • Adjustable flow pump
  • Made from plastic material
  • Black canopy

Tetra Fish Cube

Continuing our countdown of 3 gallon fish tanks, this is a slightly bigger Tetra tank than the globe that we’ve featured elsewhere on the site, so if you’re needing more room for fun things like decorations and other accessories then this should be perfect. This tank also comes with a handful of nifty features that will make it even more fun for your fish, including:

  • 3i filter to keep your fish healthy and safe
  • LED lighting system
  • Feeding hole

Tetra GloFish Aquarium Kit

GloFish make excellent products, and this Tetra 3 gallon aquarium kit is no exception. Aside from being colorful (and making the inside of the tank feel like a rave), the fish tank also has enough room for a few decorations and ornaments, plus it comes with a few extras, including:

  • Aquarium Light with Blue LEDs
  • Internal Filter
  • Medium Filter Cartridge
  • Aquarium Set-Up Guide
  • Dimensions – 14.6 inches x 8.8 inches x 11.2 inches

Tetra Half Moon Bubbler

This tetra tank is very similar to the other half moon aquarium in this post, except it has a built in bubbler! If you’ve seen Finding Nemo then you’ll know all about bubblers (remember the Dentist’s office?), but in case you haven’t seen that film, bubblers produce bubbles. That’s about it really. Luckily, the tank isn’t just all about the bubbler, it also comes with:

  • Color changing bubbler – not literally, but the LED gives it a cool color changing effect
  • Cartridge based filtration
  • Controller for the color changing

MarineLand 3 Gallon Contour Kit

Aside from looking really cool, this contour 3 gallon fish tank is full of extras that make it an awesome choice for anyone with smaller fish. The rail light feature is really cool and gives it a unique look too. You’ll also get:

  • Daylight and moonlight LED settings – creates a unique look 
  • Discreet 3-step filtration & adjustable flow
  • Filter pump
  • Filter cartridge
  • Easy access glass canopy (perfect for feeding time)
  • Dimensions – 12 inches x 12 inches x 12.5 inches

GloFish Half Moon Fish Tank

Another 3 gallon half moon aquarium! I think this shape is popular because it allows for quite a good view of your fish without leaving them totally exposed. This is another GloFish fish tank, so is similarly colorful like the other GloFish aquarium in this list. With the tank you get:

  • Blue LED bubbler
  • Air pump
  • Internal filter
  • Small filter cartridge
  • Clear canopy (perfect for feeding)

Kollercraft Betta Fish Bowl

Although we’ve included this Betta bowl in our 3 gallon list, it isn’t the most highly reviewed item that we’ve ever included. Most of the reviewers over on Amazon didn’t even realize that it would be made of plastic, which gives it a much lighter feel than they were probably expecting. However plenty of the reviews seem pretty happy with it, so it’s quite a good cheap option if you need something that’ll simply keep your fish happy. Here are the main features:

  • LED light unit
  • Impact resistant built
  • Samples of API Betta food
  • Dimensions – 11.00 inches x 11.50 inches x 11.00 inches

Kollercraft 3 Gallon Hex Fish Tank

Kollercraft are great at making fish tanks which are simple and safe, and this 3 gallon aquarium is no exception. The unique shape makes it great for getting a good view of your fish, and the wideness of the tank means you can easily include your own collection of decorations and ornaments if you like. The fish tank also comes with:

  • Internal filtration system
  • LED lighting

Hawkeye 360 Fish Tank

Aside from looking really cool (kinda like a rocket ship) and having a cool name (kinda like a jet fighter), this fish tank is pretty new to the market so is still fresh out the box in terms of reviews. It doesn’t come with much – just an aerator which keeps the water healthy.

Marineland Silhouette 3 Gallon Aquarium Kit

This is a very stylish aquarium kit with a huge amount of positive reviews on Amazon. Another great thing is that the seller on Amazon has answered loads of questions about the fish tank (more than 30!), so you can really do your research. Because it’s a kit, you’ll have everything that you need to get started with your new fish, including:

  • Hidden 3 stage filtration
  • Daylight & moonlight LED settings
  • Hinged canopy
  • Adjustable pump
  • Dimensions – 14.1 inches x 13.6 inches x 12.2 inches

Tetra Crescent Aquarium Kit

Even though this fish tank is also available in a 5 gallon variety, this is a list of 3 gallon fish tanks so we’re going to be talking about the relevant size! This is described as desktop aquarium, probably for 2 reasons; firstly, it’s likely to fit comfortably on most desks, and secondly because it has a cool little light at the top (which is sort of like a book light). We love this fish tank because it has over 200 reviews over on Amazon (and an average score of 4 out of 5 stars which is pretty awesome!). It also comes with:

  •  Cartridge filtration
  • 16 LED light
  • Whisper filtration
  • Dimensions – 14.6 inches x 8.8 inches x 11.2 inches

Aquatunes Aquarium

This fish tank was so weird that we felt like we should just add it for the fun (and because it’s also 3 gallons). I’m not going to pretend like it’s the best aquarium in this list, I mean it’s basically just a speaker and fish tank combined. However, it does have some pretty good reviews so it must be doing something right.

Elive Aquaponics Aquarium Kit

This is described as a ‘semi circle’ fish tank which gives you a clue on the shape. Aside from looking really cool (and having a plant poking out the top of it like a crazy hairstyle), there are a ton of very useful features that this aquarium has which make it an awesome choice, including:

  • Made from glass
  • Hidden LED lighting
  • Dual filter
  • Set up guide
  • Dimensions – 13.5 inches x 8.7 inches x 11.7 inches

Top Fin 3.5 Gallon Enchant Aquarium

Ok, while this isn’t strictly a 3 gallon tank, we thought we’d still include it (towards the end of the list) purely because it’s a good choice and it fits well in our list. Described as an ‘enchant’ aquarium (I guess because it’s magical or something?), this tank has an impressive score of over 4 stars out of 5 from more than 50 reviewers, so it must be doing something right. We have a similar tank on our 2 gallon page. Here is a quick rundown of the main features of this aquarium:

  • Made from plastic
  • Feeding door on hood for convenience
  • Color-changing LED lighting system
  • ‘Element’ filter
  • Available in black
  • Dimensions – 12 inches x 8 inches x 12 inches

Top Fin Aquaponics Desk Tank

Another Top Fin tank, another 3.5 gallon entry in what is supposed to be a 3 gallon list. But hey – it’s always better to get a tank that’s a little bit bigger for your fish than a little bit smaller, so a half gallon ain’t going to hurt one bit. This tank comes with a ‘planter’, which explains the crazy green hairstyle that it’s rocking in the image that we’ve selected. It’s also got other cool features, including:

  • Made from glass
  • LED
  • Pump
  • Average score of 4 stars
  • Dimensions – 10 inches x 9 inches x 10 inches

Aqueon Forge Aquarium Stand

Like all of our fish tank lists, we decided to end this 3 gallon countdown with a recommended stand. This is a highly rated stand (4 and a half stars from over 50 reviews) which would be a perfect match for your 3 gallon tank as it has a smaller lower shelf, and room for something larger on top (like a tv or even another fish tank!). Here are the main features of the stand:

  • 7 step set up
  • Reversible wood panels
  • Rust resistant coating
  • Dimensions – 28.5 inches x 18.2 inches x 5 inches
  • Weight – 15 pounds

A 3 gallon fish tank is just about the smallest size of fish tank or aquarium that we’ll ever recommend on FishTankBank, mainly because there are very few types of fish who would ever feel comfortable in a tank of this size. However, there are smaller species of fish who can live very comfortably in 3 gallons (like Bettas), so with this in mind we thought we’d create a list of the best 3 gallon aquariums and fish tanks we could find:

100 Gallon Fish Tanks & Aquariums (Kits & Stands)

If you’re serious about fishkeeping, then getting a 100-gallon aquarium is a great idea – it’s large enough to accommodate a good number of fish and extras like plants and ornaments, but it won’t take up too much room in your home and can probably sit comfortably in most rooms. If you’re looking to buy a 100 gallon fish tank then we have some suggestions you can try updated for 2021. We also offer custom aquariums at this size. But before we get into the detailed reviews, here is a quick overview of what we think are the best tanks at this size:


100 Gallon Fish Tank by FishTankBank

This tank was made by our workshop team, and can be shipped to any location within the USA. This is a 100 gallon glass custom aquarium built with a reinforced aluminium frame. Unlike popular plastic frames which are porous, aluminium frames are designed to withstand moisture. We have similar tanks on our 300 gallon and 150 gallon pages. Here is some more information about this aquarium:


  • Shipping to anywhere in the USA
