Try to get live blood worms or live blackworms. these seemed to be relished my many hatchling aquatics. You may wish to get some plastic plants to make some sort of a hiding spot. If he can hide he'll be more comfortable and the sooner he's comfortable the sooner he'll want to eat. Keep in mind he may not want to eat in your presence. Keep the water pretty clean and shallow and if he's warm he's appetite will probabaly pick up in a week. Good luck!
