I have a hot and cool side, with my hot side at around 84 ambient, and 88 on the surface of the substrate. The cool side is much cooler, being around 78 ambient, and MAYBE 80 on the surface. Thor is constantly on the cool side, and it worries me a bit. I've read in one of my python books that they do well in temperatures of anywhere form 76-88 or something. But then others say that they shouldn't be below 80 even on the cool side.
One of my books says that pythons need a fluctuating day/night temperature to do well in captivity. By this I mean ~5 degrees cooler during the night. But then I've seen people on these forums say that they need a constant temperature regardless of day/night. This doesn't make sense, as in the wild the temperature naturally drops at night. However, I know BP's burrow into termite holes and such to keep warm, so the lower nighttime temps might not even make contact with them. I've been dropping my nighttime temps by 3-4 degrees since I got him.
Why is there so much mixed information out there? Its kinda annoying to be told 3 different things, especially when the info is coming from 3 different professional herp breeders/keepers.
