If he's not eating when offered with a hide, removing the hide won't help either.
Did the seller/breeder tell you if he was eating f/t or live before? If he was eating f/t before and is now refusing, you could post a couple pics of your setup and what equipment you're using. If he was eating live, you may need to buy live rodents for now and it may take a few more tricks and some time to convert him to f/t.
