Mine would "Bask" for 10 minutes or so when I had a black light above his limb, but ever since I switched to infra red I have yet to see him do it.

And speaking of going behind the hide, this morning when I got up Monty Joe was coiled up outside and behind his cool hide. This is a first since I have had him. Took him out and held him just for curious reasons (due to this) but he was as happy as he ever was. Put him back in and now he is just laying half on his cool hide and half up in the air on his limb.
