7 TOP Rimless Aquariums: Seamless, Edgeless, Frameless Fish Tanks

What is the best rimless aquarium?

You can achieve a much better look with a rimless aquarium than you can with a framed tank.

Rimless tanks are simply made of glass and silicon, resulting in an unobstructed view of your fish and plants. Framed tanks obscure large parts of your fish tank and prevent you from being able to enjoy it from all angles.

Don’t get a fish tank with a thick frame, choose a seamless aquarium without rims. After many hours of research, here are the best rimless tanks that you can buy online!

The benefits of a rimless tank include:

  • Unobstructed views into the tank
  • Easier access into the tank
  • Easily see the water line for top-ups
  • Easier to clean as gunk doesn’t adhere as much to the corners of a rimless fish tank as to the bracing on a rimmed tank

The best rimless fish tanks are made from a special type of glass, quite different than regular household glass.

It is a higher quality, low iron glass which gives a higher level of transparency and clarity. Low iron glass takes out the green-blue hue that can be seen in some thicker glass products.

You also want to look for an aquarium brand that is known for superb silicone work (with aquarium-safe silicone). There is nothing worse than getting a new tank with messy, poorly finished silicone edging.

Generally speaking, if a tank is made in the US, it will have been completed with a high level of craftsmanship.

Here are our top 7 picks.

Rimless Aquarium

Rimless aquariums are much nicer than thick-rimmed tanks and create a much better impression.

When the rimless tanks are constructed by a reputable manufacturer, there is no reason to worry about leaking silicone seals.
