I keep all my amphibians between two rooms at the moment. I have a "warm" room and a "cold" room set up here in the basement.

I just bought a new house, and currently have some serious construction going on in the new Critter Cave in the basement there. Then, I will have my cool temp amphibians on one side of the room, and my warm temp amphibians on the other with my office sandwiched between the two.
