How did you try feeding him? What sort of setup is he in?
After my babies shed for the first time, I waited a week to offer them their first meals so they would be nice and hungry. When I did feed them, I waited until evening, I put them each into small deli cups, and left them alone for half an hour in the dark. Then I heated up a frozen tiny pinkie really hot, dropped it into the containers, and then left them completely alone in the dark again for an hour. They all ended up eating the very first try, but if any of them hadn't, I would have reheated the pinkie and left it with them overnight. That's what I suggest you try first, but if that doesn't work, Nanci has a great list of feeding tricks:
