Thank you. That makes a lot of sense. We have done a lot to try and keep more heat in the tanks as all sides except the front are covered (top is covered by foil except for maybe 1/4 of it for the heat lamp, and the rest is covered with padded poster board). I guess I will start building a rack of some sort... now another question about tub size. I have 3 snakes, a 2300+ gram female and two that are about 700-800 grams. What size tubs for them?

Thanks again for the help
