what have you been trying to feed it? Try everything, and try it all again the next day maybe skip a day and do it again. I have a small sea foam pac man, and when you try to feed him from tongs he wont eat, I was really getting concerned about what he was living on when I realized he must have been eating some of the crickets I thru in or worms because he was getting bigger. If he is hungry he eats he just doesn't eat as often as the AFB.... you dont know what its eating habits were before and if it wasnt happy then its eating pattern wasn't good before just be patient.
