I recently got my first White's Tree Frog about 4 weeks ago. For the last week he has done nothing but lay on the substrate in a hibernation type state. He is a very rich dark brown right now and wont move at all unless I am cleaning something and move him aside. After doing this he will open his eyes for about 5 minutes then go find a new spot to lay. Before anyone asks here is what he has to live with. He is in a 29 gallon by himself the temp has been about 82 in the day and around 75 at night. The humidity level is about 60 %. Do White's Tree Frogs have a hibernation period? Is there anything else that could cause this?
