My herimet crab Tiny has always kinnda hidden in other shells and under my other hemit crabs and refuses to come out of his shell when he knows i can see him. Today I noticed what looked like a molting "tunnel" under the bath shell. I've never had a hermit crab molt and don't know what it looks like . Hoping its not a molt 'cause h e and his three other buddies were supposed to particapate in a science project. Finding there way through a maze not like testing soap and stuff... any advice would be very helpful thanks.
