Do not put oil on the tail, the scales will all fall off! The tail may end up being more of a problem than you may think. He will not be able to shed in that area correctly and it may eventually cause strangulation of the tail that is curled. No oil, and watch for sores or discoloration. Try to get as much shed from between the crevices as you can using warm water after he sheds the rest of the body. As he grows, the coils may become tighter and more of an issue, or maybe not. You will just have to wait and see.
