hey man...
just make sure the sally lightfoot wasnt munching on the molted remains of a hermit. hermits that are growing molt frequently, leaving behind a "corpse" that looks like the hermit is dead. i'm sure this "corpse" has some nutritional value as i have seen my emerald crabs, shrimps, and other hermits scavenging it for whatever nutritional value it may have. more than likely, it's just a castoff shell of a hermit and not really the hermit...hope this helps......
