I have had blood pythons for almost 2 yrs now, I am by no means an expert but I did attend the symposium in daytona on bloods a few years ago .

Anyway, we keep ours in a rack that has no heat. They are in the bottom 2 shelves and they have a big HEAVY water bowl filled with water at all times, sani chips as substrate and their temps are ambient room temps that range between 82-85 in the summer and down to 76 in the winter. We have never had any problems with our bloods.
