Chitons all curled up

[justinl]

this is a natural defense posture for chitons but it probably shouldn't last for weeks on end... pick them up gently and give em a sniff. if they stink they're dead, if not put them back. Do snails live in your tank okay? if they do then I would imagine most chitons should fare just as well as any snail. In which case, just give them more time i guess, and give the sniff test every few days.
