So I searched and only found one thread with little to no info on the subject.

Anyways, I have (2) 20gal L tanks set up on this wire shelf thing, one on top of the other. I have to have a good 8-10 inches between the bottom and top tanks to open the bottom one.

What I was wondering, is if it would work to turn the tanks on their side, so the mesh top (soon to be plexi glass or something clear with vent holes) would now be the front of the tank. They are locking lids, so I figured out a way to have them still slide in and lock, so escaping isn't a problem.

This would let me have the shelves closer together, kinda like a rack system, and eventually fit more tanks/tubs/whatever-at-the-time onto the same shelf.

Has anyone ever done or heard of doing this? Suggestions?
