I think checking on him that frequently could be stressing him too. He needs time to settle in. Can you see his water, without going in and bothering him? If so, I would stop getting in there twice a day. Just go by and peek if you need to, without disrupting him. If you give him fresh water, it should ne fine for a couple days. Little hatchlings can get stressed really easy. Also, make sure he has snug fitting hides, that will help him feel secure.
