If you are looking for a modern, sleek, and simple fish tank, then you might be interested in what a rimless (also known as a “seamless”) aquarium has to offer. These tanks are made of ultra-clear low iron glass and have no bulky plastic brackets or thick rims that often stand out in standard glass aquariums. Rimless tanks may be on the pricier side, but they are definitely worth the investment if you want a clear and attractive-looking tank to turn into a lavish aquarium with either freshwater or salter water fish and plants.
We have reviewed some of the best rimless tanks on the market and chosen them specifically for the quality and features these tanks have to offer.

Buyer’s Guide: How to Buy the Best Rimless Aquarium
What is a rimless aquarium?
Rimless aquariums are constructed of low iron glass that gives a higher level of clarity and transparency to aquariums in comparison to the blue-green hue that can be seen when you look at the glass panels of standard glass tanks. This enhances the visual appearance and sleekness of a rimless tank, and they look less bulky and thick than normal glass. Most low-iron rimless aquariums will have a high-grade silicone to connect the panels.
There are many different types of rimless aquariums, such as plain ones or combo sets that include a filter, heater, or light. Most rimless aquariums will include a leveling mat that can be placed underneath the tank to avoid putting excess pressure on the delicate glass panels.
What are the benefits of a rimless aquarium?
A smooth finish and neat appearance to the aquarium
Unobstructed view
Easily notice when the waterline has evaporated and needs to be topped up
Less dirt and dust attach to the aquarium
Made of higher quality low iron glass rather than standard thick glass
