I have no pic, but I will explain my horned frogs' seperate tanks.
Each frog has its own 20-gallon-sized long tank. There are a few inches of forest bed (coconut fiber) substrate, enough so the frogs can bury themselves fully. There are water bowls in each tank (the larger femals has one big bowl, the smaller male gets two because he is smaller and the tank is big.) Each bowl is recessed into the substrate, so the frogs have an easier time of entering/exiting. Each tank has backgrounding on 3 sides to provide "privacy" and security.
I don't use heat lamps; the temp in my frog room is always correct for them. I really don't think they require lighting anyway, being buried all the time. The natural light from the window is sufficient. Never plave the tank in the direct path of sunlight, though; you could have Baked Frogs! Please don't get an undertank heat pad; frogs bury themselves to cool off in warm weather, and that defeats the purpose, plus it ges WAY too hot.
Any more questions, ask away!
