I am switching to tile for my enclosure (40 gal breeder) and I have 2 12x12 1 10.5x12 2 5x12 and 1 5x10.5 as i saw in a previous posting. my only problem is i cannot figure out how to position them for the life of me. any help would be awesome thanks!
I don't know the exact dimensions, but I'd think you'd need some gaps if you are going to be taking them in and out. Also the silicone on the inside edge will prevent them from sitting flush on the bottom (i think).
