SeaClear 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

  • 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 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.
