I had read once that you can have too much humidity (not sure in this case, but just to relay information). I didn't think too much of it, however my red has been having massive shedding problems on his hine legs and tail. It looks very dry and old, as well as caked on and seemed to become a large problem. I bathed him regulary raised the humidity and nothing seemed to pull through. The skin was strong and still attached, but you could tell by the thickness and the tightness that it must have been atleast 3 sheds worth. Over time I let the humidity levels drop naturally. It seemed the skin, slowly dried out, and started cracking, which then I have been able to aid him in pulling it off. his hine legs shedded by themselves with the drop in humidity, but the tail I had to help him with most of it. Looks great now though at 100% completion of shedding... untill next time.
