HCA: Hermit Crab Association

Today I found a little tunnel underneath the fresh water bowl, Shelldon was down there, and when I saw him, his colors were a bit odd and he barely moved, he was slightly sticking out of his shell, too. He's been down there for a month, the moment I realized it was him I put the water bowl down right away, will he be okay?

Sounds like he's probably molting. As long as u didn't pick him up he should be ok. Just let him do his thing.

Also, as hard as it may be, don't try to disturb him too often as well! When moulting, they normally prefer to have some 'me time' and appreciate the space.
