Making Rimless Aquarium Diy. Unlike wood or metal, glass at 3/8 does not like to have small cuts made in it. I watched a few youtube videos on diy rimless aquariums which left me with two options.

This aquarium is constructed with the two end pieces of glass fit inside of the back and front. Diy screen tops are very inexpensive, extremely easy to make and will keep your fish inside your aquarium where they belong. I would not trust one without a rim.
