I have a small tank (20" long x 10" wide x 13" tall) and I don't know what to do with it. Any kinds of reptiles I could house in it? It seems as though it'd be too small for anything other than a baby lizard of some sort. Not currently keeping any lizards at the moment and sold off my larger tank (shouldn't have). I'd like to keep something in it but if there's no species that'll fit it I'll simply sell this one off and buy a larger sized cage.
