Yep...he made need time to adjust and the fact that he is getting ready to shed might keep him from eating too. Most of my new snakes wouldn't eat when I first got them...and some will not eat during shed time. You might also consider fish fillet. I do feed fish..but not live fish. I go to the seafood counter at my supermarket or to a seafood store and buy fresh, never frozen, fish. Tilapia is good, farm-raised rainbow or steel-head trout is good too. Just make sure you are feeding other things besides fish...a varied diet is best. I cut the fish into small pieces and freeze what is left...then thaw the rest when feeding. Always feed it raw...never cooked.
