HCA: Hermit Crab Association

Ok, so I had a mass molt recently, and everyone is coming up one at a time (thank goodness). I did notice however that one of my E's came up on Monday, changed shells and went back down. I haven't seen her since. Is this normal and should I be worried?

Also, I had a very small one go down over a month ago and I'm worried he didn't make it. His name is Yoda, and he is a 'small' PP. Think he's alright or should I prepare for the worst?

I would assume everyone is ok.

If you don't smell and 'fishy' smell yet it will do no good to worry about anything. I had a small pp down for 3 months and he didn't even molt. As for the one who just molted he may just like digging. I have a hermit crab that I only see at night and all day I hear scratching on the bottom of the tank.
Just make sure their food and water is full and they do the rest. I know it's hard but hermit crabs defiantly teach patience :roll:
