How long since you last tried, don't try more often than every 5 days. If he hasn't shed then don't be surprised if he doesn't eat. I'd probably leave until after shedding personally.
ok i will follow your advice i only try and feed him once every 5 days sometimes longer ill leave him till sat and see what happens then the guy in the rep shop has asked me to take him in after shed and he"ll assist feed him so if he doesnt take it on sat im going to go down that road i think
