I recently adopted a 2 1/2 year corn snake thats 3 feet long. She is temporarily housed in a ten gallon with a heat lamp until i can get her a bigger one (cant for a couple weeks due to work schedule). The snake always stays on the cooler side of the tank with is 77 degrees. The hot side is 83. my big concern is i have a half circle tree trunk that i bought at petco for her hide. the temp measuring off of that is 120 degrees!!! its cooler inside (79). could this be why she stays away from that area even the the substrate temp is 83 and inside is fine, just the top of the hide is hot? I will be soon getting her as bigger tank and a heat pad, but for now this has to do as the adoption came up quickly and i didn't have the time to prepare for her.
