Coworker died and his hermit crab needs a home... how do I care for it?

get him another shell and just put it in there he will change sheels but after he does so take the old one out and get rid of it.....they like sand or moss as a bedding....make sure he has a feed and water cap.......and buy sone crab food for it......dont let it get to hot or it will die....they are easy to kill.....so watch out..
