HCA: Hermit Crab Association

Whenever I check the tanks at my local pet stores, they're empty or all the crabs are hiding, so I don't understand how other members here seem to be able to identify when a batch of Es arrive. Is it just that they're so much more active? Trust me, if I ask the employees around here about different ...

There is enough oxygen exchange through the sub for them to survive. That's good to know! I now feel r...

One of our new hermit crabs burrowed down soon after coming home, and when we came back a few hours later he was gone, and there wasn't even a hole in the ground where he was digging.
