Checker board wrass ate my hermits

[justinl]

eh. hermits are overrated anyways. Wrasses, especially the larger species, are carnivores after all; this sort of thing happens. I'm sure there's a size refugium for hermits and other arthropods relative to the size of the wrasse but what that is, I have no idea. Do you have a role that absolutely needs to be filled by hermit crabs? if not, then don't worry about it.
