That would make sense. I haven't seen him shed yet or seen any sign of skin in the tank. I do, however, maintain a humidity between 60 and 70. Sometimes it goes as high as 80.

I also read somewhere on this forum that a calcium deficiency may play a roll in the paralysis.

The "bloody ring" seems to be under the skin and I checked him for lumps when I got home and found nothing other than things I determined to be bones (but I'm not expert).

I took two more photos after I examined him in the hope that it may reveal something externally.
