For about a week my hermit crab (Mr.Echo) has been digging and not moving much. I didn't relize he was going into a molting stage, so I took him out from under the little water bowl. I did my research on hermit crabs and have the proper conditions. The lady at the pet store hadn't told me that I needed sand for molting crabs. He is in a shallow (empty now)water bowl and I don't know if I should move him. HELP!!!!!!!!!!!!!!!!!!!!!!!!!
