This happened with my male before I gave up on using tanks. I'm not sure what caused it exactly, but I'm assuming it was because the humidity was always low and he never had good sheds. I doubt that the bleachy substrate had anything to do with it initially, but it could have made it worse.


What is your set up like? What are your temps and humidity, and how are you measuring them? How are you heating the enclosure? If you have everything at it's optimum settings then he should have a full shed (one piece) and they should go back to normal.
