It has only been the last week or two that my tank has had excellent conditions, and I think Seacil went down to molt yesterday! He is down about 2" in one corner of the tank. I put some sand over him to see if he came up today at all, and he hasn't. I am gonna try to section him off some from the other two so they don't dig him up by accident. Is there anything else I should know or do to keep an eye on him?
