I used to use the black heat "night time" bulb when I first got him - but once it burned out I switched to a CHE on both sides of the cage. I don't get to see him as much at night, but I'm also not up as late now that I am out of collage. He also *loves* to wedge his head in the grove of the sliding glass door of his AP cage and the only way I can prevent this is to hang a dark towel over that side of the cage (on the outside). He seems to think this makes it a solid wall and moves to the other side to surf the walls where his head does not fit...snek not that smart
he wall surfs from about ten pm to midnight then goes back in a hide. Does it longer as he gets hungry, but usually once the "curtain" comes down he finds somewhere else to be. So I can't actually see him even if I had a night bulb
