Yeah... just make sure you keep the temps right and provide him what he needs. He'll probably settle in soon - probably just asserting himself in his new home.
Unless he looks ill I wouldn't worry just yet. If he's basking, gaping and able to move around without trouble, he 's probably fine. If you're worried about his food mot being digested then wait a couple more days or so and see how he acts and if he has a poo. If no poo and you're still worried then give him a shallow, luke-warm bath and maybe even give his tummy a gentle massage.
He's probably perfectly fine though. Most beardies take a week or so to start settling in to their new homes and males especially will be asserting dominance to anything that moves (hence the beard puffing out).
