It’s a female I think and a neo. The coloration usually happens as they get older. How long have you had her for? As they age they molt less often so it could be she’s just old. They also will sometimes eat their own molt. It’s the GH that’s important for their molting. Get a liquid test because the strips are less accurate and unreliable. GH should be 6-8.
