I'm actually a snake guy by choice but I have to compromise with my fiancee on something because she isn't into snakes, so I'm thinking frogs would be pretty cool. So, is it okay to house multiple species together? If so, which species do best together? I was thinking since it is such a large tank (55gal) that there shouldn't be any territorial problems. Or maybe something like dart frogs and tree frogs would be fine since they would occupy different parts of the tank. Please help me out, this is a completely new world for me. Thanks in advance.
