Hey I just noticed today that my red has lost one of his nails. It is the "thumb"ish one on his hind legs. His humidity is kept high and temps are closely monitored. He is fed cod liver oil and a varied diet and he has never had shedding problems. I also noticed that the same nail on the other hind leg is looking like it is going to fall off. I was wondering what is causing this? He hasn't had any problems and is growing insanely fast! I was looking at pictures of other tegus and it seems a lot of them are missing this nail as well.
