Rimless aquariums, sometimes referred to as "seamless" aquariums, may be of interest if you are looking for a sleek, modern aquarium.

There are no plastic frames or thick borders that interfere with the crystal clarity of these super clear, super clear iron glass aquariums.

Although rimless aquariums are more expensive, they are well worth it if you want a crystal clear tank for tropical fish and exotic plants, whether they are from freshwater or saltwater.

For the quality and features these rimless tanks offer, BestForPets (bestforpets.org) has reviewed and selected a few of the best rimless aquariums.

How to Choose the Best Rimless Aquarium for Your Money

Defintion: What is a “rimless” tank?

Standard glass aquariums have a blue-green tint to its glass panels, whereas rimless aquariums are built with low iron glass, giving them a better degree of clarity and transparency.

With this, rimless tanks seem sleeker, less bulky, and thinner than regular glass tanks. The panels of most low-iron rimless aquariums are connected using high-grade silicone.

A wide variety of rimless aquariums are available, including those that include a heater, a water filter, and a light. Tanks that do not have an overhanging lip usually come with a leveling pad that may be used to keep the glass panels from being strained.

What are the advantages of an aquarium without a rim?

  • An aquarium with a smooth surface and a tidy look is desirable.
  • A clear vision without any obstructions
  • You can easily tell when the water level is low and needs to be replenished.
  • The aquarium is less likely to accumulate filth and dust.
  • Instead of conventional thick glass, this version is made with higher-quality low-iron glass.


The LANDEN 20C Frameless Low Iron Aquarium is our overall favorite rimless aquarium as it comes in a variety of sizes, is made of high quality low iron glass and has a clean and simple design.

To start a saltwater aquarium, we recommend the LANDEN 40C Borderless Aquarium with Rear Filter Room as it has everything you need and is still reasonably priced.
