My temps are normal.. about 90F on the warm side and then the cool side would be whatever the temp in the room is at the time.
The hide on the warm side is big enough to have him squish in there comfortably with a bit to spare, the cool side hide is about twice the size of him balled up.
He does spend a good amount of time in his hide during the day but it seems he does come out and sit on top of the hide or just beside it a lot too.
Oh, and the actual hides I'm using are these ones http://www.livefoods.co.uk/images/hideout-new.jpg the small and the medium size.
