Hi. I'm relatively new to crested geckos, and I'm a bit concerned about a new one I got just recently. When he stands or walks on flat surfaces, he curls his toes up so that he's walking on his "palms." There's not wrong with the toes, he uses them when he climbs, and sometimes walks normally. He doesn't have trouble sticking to things, and there is no stuck shed on his toes or anywhere else. He is active and has good body weight, and the husbandry his previous owner described seemed correct. I've never seen any of my other geckos curl up their toes like that. Could this be a sign of some problem, or is he just weird?
