Buddah is now a little over 5 months old, I recently changed out his heat light for a daylight heat bulb and now only have heat on for 12hours so I have lower temps at night. Anyways recently I see him with an open mouth and I'm not sure if I should be worried. I have heard people talking about their chams having their mouth open. In the best basking spot its 90 and in the coolest part of the cage its like 75. I'm guessing it has to do with the new light or maybe he's just getting older and tougher?? He is behaving perfectly normal otherwise so I just want to make sure that this isnt a bad sign.
