We recently had a power outage, and I was concerned for my snake. I was wondering what kind of temps they can handle. It must be pretty cold since they live so far north. My condo went down to 55 degrees during the outage, but as soon as we lost power, I covered the top of the tank with a thick, doubled up towel. There is a large rock in his tank on the warm side, and according to my temp gun, the rock didn't get below 60 degrees and the tank temp was 58 degrees.
