Well I looked down and my 2 year old red foot hatchling, Vlad, bent her fingernail backwards!!! Her eyes looked sad. But by the time I rushed back to trim it off, she had already lost the poor front leg fingernail. So I gave her a nice soak and an oil. It is all from the moisture in her soil being excessive from me pouring in to much fun water. I learned today why they like a dry top layer better.
