Congrats! It's an awsome feeling when a snake eats for you for the first time. Such a relief!
Due to the fact that you just got him yesterday, i would now leave him alone for about 5-6 days. You are supposed to wait about a week after placing a snake into a new home to try to feed, but in this case your snake ate. So giving him 5-6 days will help him become even more comfortable and help him adjust into his new environment. I know its hard to not get him out and hold him, but its for the best. You don't want to increase his stress level, he did just get moved into a new home.
Good luck!
