Hermit crabs are nocturnal, so you might not see him/her playing around.
If your hermit crab is inactive when you pick him/her up and/or during baths, get some water into his/her shell (not a lot) and your crabby might come out. If you have the HBH soak & spray mist, that works well too. If that doesn't work, that's ok. As long as your crab doesn't smell like fish and moves a little (even opening his/her claw)
