So I am going to give Otis the Russian more heat until his owner decides to keep humor not. I put him in a 40 gallon tank. Took him out of 20 she houses him in. His bulb is not warm enough. At Petsmart. What do I get? I have aflourescent strip for light.m v b with u v b or mercury vapor? Coconut coir for substrate? He currently has reptibark. Do u think i can put him in the enclosure dad and I built until a decision ismade or will that contaminate it if I get a baby? Thx. Lynette
