The Best Rimless Fish Tank – Big & Small Rimless Aquariums

A rimless fish tank achieves a look that other types of tanks cannot. This type of tank simply consists of glass and silicon, resulting in an unobstructed view of your fish.


I remember one fish tank I had with thick rims around every corner. Whoever constructed it had obviously forgot the purpose of a fish tank – to see and enjoy the fish! What they had made was more like a box with windows. I had to go right up to the tank and peer in between the rims. I was the fool for buying it!


Don’t be like me, choose yourself one of the best rimless fish tanks listed below, and enjoy your fish as you should!

The Best Rimless Fish Tank Aquariums


The benefits of a rimless fish tank:

  • 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

Low Iron Rimless Aquariums

How To Make Your Own Glass Fish Tank


The other option, instead of buying, is to build your own rimless fish tank. I’m not going to give you a tutorial myself because this is a project I have not yet undertaken (though I would like to try!). Here are a few of the top ‘make your own fish tank’ videos from YouTube.


This first video is an in-depth ‘how to build a glass aquarium’ tutorial. It’s about 20 minutes long and emphasizes the importance of  getting everything level and properly squared, and how to make a nice silicon bead.



This next fish tank tutorial is also very helpful. It is video only (with music overplay), but it can be followed step-by-step. Make sure you have plenty of tape on hand!
