Berber Skink

Question
I have had my Berber skink since January and still haven't seen him eat. I rang the pet shop from which I got him from and they said he will be fine once he has settled in. I feel he has settled in how as he will happily come to me when I open his viv etc. I have tried him with Crickets, Lettuce, banana, grapes, and some little worm things. But still no eating. The temperature in this tank varies between 91 and 94 depending on the time of day. I read that this was correct, and would maybe get him to feed.

Please help as I am starting to get very very worried.

Thanks

Answer
 Has he been seen by a good reptile vet yet?  Sometimes after a bout of relocation stress, there is a rise in gut parasites and that may have caused gastrointestinal distress.  If he is put on an antiparasitical medication, follow it with a probiotic like Acidophilus to replace the gut flora he will need to help digest.
