30 Gallon Fish Tanks & Aquariums (Kits & Stands)

A 30 gallon aquarium is a good size for an intermediate fish keeper – it’s small enough to fit in a home, but large enough for a good number of small to medium sized fish, and a few ornaments too if you want to add some style. Smaller than a 75 gallon aquarium but larger than a 5 gallon aquarium, a 30 gallon tank is the perfect size for lots of people. Before we get into the detailed review, here is an overview of the average cost, and here is a quick overview of the best tanks at this size:

And now for the detailed guide:

35 Gallon

Aqueon Acrylic Aquarium

We love the Convex shape of this aquarium, which not only gives it a unique look, it also enhances viewing. Many of the reviews mention that it is lightweight but strong (due to the acrylic), and it is fully leakproof. Another highly rated fish tank, and another that has a ton of cool features:


  • Made from acrylic (lighter and stronger than glass)
  • Available in 3 colors
  • LED fixture and reflector in lid
  • Available in 3 colors (black, blue and cobalt blue)
  • Suitable for saltwater and freshwater species
  • Dimensions – 30 inches x 15 inches x 21 inches
  • Shipping weight – 31 pounds


Clear-For-Life 35 Gallon Hexagon Aquarium

Clear-For-Life make tanks and aquariums that look excellent, and this hexagon tank is no exception. At 35 gallons it’s perfectly big enough for smaller fish, and a great thing about this tank is that it qualifies for free shipping. Other notable features include:

  • Built-in filtration
  • Made from acrylic (stronger and lighter than glass)
  • Dimensions – 25 inches x 21 inches x 24 inches
  • Available in black

Seapora Cube Aquarium

The image used for this 35 gallon aquarium isn’t exactly flattering and makes it look pretty boring, but judging by the reviews this is a seriously awesome fish tank. The seller has been helpful and has answered a few common questions which are worth a read. Here are the main features of this tank:

  • Made from glass
  • 4 star rating
  • Good price
  • Cubic shape
  • Dimensions – 20 inches x 20 inches x 20 inches

Vepotek 35 Gallon Fish Tank

Vepotek make beautiful looking fish tanks, but not affordable fish tanks. This is a great example of that. There is no denying that this is both a nice looking 35 gallon aquarium and a well made aquarium, but if your budget is tight then I’d probably avoid it.  Here are the features:

  • Made from acrylic
  • Includes light
  • Includes water filtration

Innovative Marine 30 Gallon NUVO Aquarium

This is a 30 gallon aquarium from Innovative Marine. The main features of this tank include:

  • 4 and a half star rating from over 15 reviews
  • Built with ultra thick 8mm high clarity glass
  • Leveling Rubber mat
  • Dimensions – 36″ x 15″ x 13″
  • Diamond edge polished
  • Black silicone

AquaTower Rectangle Aquarium

We’ll be honest, we’re not entirely sure that this 30 gallon aquarium tower is worth your time or your money. Aside from not looking that good, it also has some pretty poor reviews from buyers (only 2 out of 5 stars). It’s also ridiculously expensive! Probably the only positive that I can draw from this fish tank is one of the funny questions that a user asked the seller – ‘Can a man fit inside it?’. I dread to think what that guy had planned.

Coralife Biocube 30 Gallon Fish Tank

The 30 gallon BioCube from Coralife is a clever ‘all in one’ system that makes it really simple and easy to get started with your fish. It’s not just a good looking tank, it also has a load of awesome features, plus it’s been very well reviewed by people who’ve bought it (it has a rating of 4 stars from more than 90 reviews). Here is a rundown of the main features:

  • Made from glass
  • Perfect for reef set ups
  • Front feeding door
  • LED lighting system
  • Filter pump
  • Rounded corners for perfect viewing

Coralife BioCube 30 Gallon Aquarium Starter Kit

This Coralife BioCube is essentially the same as the other 30 gallon Coralife fish tank that we included in this post, except this is a starter kit, which means it comes with a few extras that make it a perfect choice for beginners. Like the other Coralife aquarium that we included in this list, this tank is very highly rated and has an average score of 4 and a half stars from over 30 reviews. Here are the main features:

  • Vibrant LED lighting system
  • Built-in filtration
  • Submersible pump
  • Dimensions – 20 inches x 22 inches x 21 inches (cube shaped)

JBJ Nano Cube RL Rimless Biotope Aquarium

This is a cube 30 gallon aquarium, which is becoming an increasingly popular shape among fish keepers of all levels. When you look at this tank from JBJ, it isn’t hard to see why this shape is so popular. The main features of this fish tank include:

  • Made from 8mm thick glass
  • Tempered glass lid
  • 3 stage filtration system (to keep water crystal clear)
  • Dimensions – 24 inches x 20 inches x 17 inches

Innovative Marine 30 Gallon NUVO Aquarium

This is a very highly rated 30 gallon aquarium, with 4 and a half stars from over 15 customers. The reason for the high rating will be that despite the high end look of the tank and the variety of features, the tank is very modestly priced. The main features of this fish tank include:

  • Made with ultra thick 8mm glass
  • Diamond edge polished
  • Black silicone sealing
  • Customizable filtration system
  • Pump included

JBJ Nano Cube 30 Gallon RL Rimless Biotope Aquarium (With Stand)

This is very similar to the 30 gallon cube aquarium that we’ve included higher up in this countdown, except this tank actually comes with a stand (which is very useful). The quality of this tank is once again reflected in the reviews and ratings, which are currently 4 stars from more than 10 customers. It’s a rimless tank, which allows you to have a truly panoramic view of your fish. Other notable features include:

  • Made with 8mm bent glass
  • Dual pump system
  • 3 stage filtration system
  • Comes with black stand


Altra Furniture Harbor 30 Gallon Aquarium Stand

This aquarium stand is actually designed to hold a fish tank that is around 37 gallons in weight, so you can be safe in the knowledge that this stand will more than comfortably be able to hold your fish tank (the maximum weight capacity is 350lbs). The stand also has space underneath to store accessories like fish nets and food. The stand has an average score of 3 and a half stars from over 25 reviews, so it was fairly well received.

Innovative Marine Aquarium Stand

We actually featured this stand over on our 40 gallon page, but we loved it so much that we decided it would be perfect for a 25, 30 or even 35 gallon aquarium. It has a really classy look, and has loads of space to store any extras that you have with your fish tank. Special features include:

  • Laminated wood
  • Can support over 400lbs in weight

A 25, 30 or 35 gallon fish tank is probably most accurately described as being 'medium' sized, and is probably the kind of aquarium that most fish keepers will be looking for. We created this list of the best 25, 30 and 35 gallon fish tanks that we could find, and hope that you'll find the many hours of research we've spent on this post useful! If you're looking for something bigger than 30 gallons then feel free to take a look around the rest of the site for larger options (we've referenced a few within the post).
