He's in a 40 gallon breeder tank. I'm still trying to maintain temps which I find hard to do. I'm using a newspaper substrate. He has a heat pad and I have a cardboard box on top of it but he's decided to squeeze between the box and the back of the tank. I'm not sure if he's even getting any heat from his belly. The bell temp is 92-93. That side of the tank reads 80 and the other side is 77 and his humidity is about 56. Also the previous owner said he hasnt eaten since May.
