They do. He stays in his hide any time there's light or people in the room, but I find plenty of evidence of his overnight exploring throughout the enclosure. All I have to do to get him out is remove his hide, give him a minute to wake up, and then get him out of the tank. He's starting to become comfortable with me, as you can see. After a few more weeks maybe he'll feel more comfortable coming out into the open, but I haven't had him for very long and he's already on his second enclosure. So he hasn't had a chance to settle in yet.
