HCA: Hermit Crab Association

Ok so my pp, Spider always threatens me in the weirdest way. Whenever i walk up to his tank to fast or pop my head in to fast he acts like his going to take off his shell. Once i ran up to his tank and he kept inching his shell off very slowly. I guess it's just his weird way of getting you to go away. He is new but i was just wondering if it's normal. Have your crabs ever done that?

None of mine have ever done that before. Are you sure he is trying to take his shell off? Hmmm... strange. Can mites make hermit crabs look like they are itchy? I've never had mites in my hermit crab tank but that is the only thing I would suggest to check out. I could be wrong though, I've only had my hermit crabs since December last year so I'm pretty new to this hermit crab care.

Well i know he doesn't have mites, and yes i'm sure he's taking his shell off because i could see his abdomen.

I've had mine slowly pull the shell back like that, wiggling it little by little back until I can see their abdomen, but never when I've just come up to the tank....that seems counterproductive. I've always taken it as either they are hot or are dumping something from their shells. Not sure why your guys doing it when you spook him though, mine just suck themselves in or run away.

Well it doesn't really matter anymore he's dead.
