30 Gallon Fish Tanks & Aquariums (25-35)

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

  • 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.

  • 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

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.

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.

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).
