Okay. My terrarium is the perfect temp now. 90 hot side, 80 cold, with a humidity a little over 50, which is a little high, but its freshly wetted coconut bark. Each side (warm and cold) have a hide, and the cold side has a 8" tall thermometer/hydrometer. Its a great one with a probe the goes to the warm side. Anyways, I came home today to find my BP sitting on top of it with his neck stretched out towards the center of the cage. For the life of me, I dont know what he was doing on there. There was no heat lamp or anything to attract him. Was he going for fresher air, or trying to cool down, or do they just like to be up high :S?
