My 2 corns are in an unheated spare bedroom (it's around 65f). They have a heat mat under one end of the fish tank they're in, and they've a choice of hides at that end even with some flat stones to transfer some heat through the substrate. But they're choosing to curl up in a corner of the cold end. I thought they liked to keep warm, so why are they choosing to be cold.
I'm just curious, so thanks for any responses.
