I have my 2 in a 30 gal Rubbermaid. I cut the entire middle out of the lid(I keep what's left of the lid on since it helps stabilize my lamp that is clamped to the side), and they are flourishing. I went to Home Depot and got a 6'x4' thing of outdoor carpet and just cut it as I need it, I believe it was only $6. They have so much room it's unreal. Mine drink straight out of the dish, well at least the female does, since I've seen her in action. They both eat out of my hands, even the male has started to and he's extremely shy.
