temps are wrong. should be 90-95 on the hot side. otherwise, it will not be able to digest.

Up the temperatures for sure. As for it being grey, it might just be in shed. Has it shed for you since you got it?

well yah i thought it was shed too im gunna up the temps with a heat lamp that im gunna get and yah he has shed since i got him and when i got back i found some shed........ and i fed him last night and still hasnt regrugtated...... one more question when i got him he was captive bred and he was very friendly at the store and when i got him they said he was very very docile but that all changed when i brought her/him home id take him out of the sand and id hold him .he/she would move in my hand and id move my other hand so he/she wouldnt fall and then would strike at it.this has happened since i got it. but didnt happen at the store ive been bitten at least 5 time now i wear gloves do u know why this happens any body
