To make sure he is going into brumation please go over your surface basking temps and how your taking them and your UVB -- is it a coil or a long tube fixture --- brumation can be mimicked by incorrect basking temps and incorrect UVB --It appears my breaded is starting into brumating. Read several sites with conflicting info on weather to leave lights on and food in the cage during this process. Can you clarify this for me?
