Reef safe?

Don't pull apart your liverock. Instead, set a trap for the crab.

Get a glass from your kitchen, that will be tall enough that he can't crawl out. Put it in the tank, where your crab can get into it from the liverock, but hopefully your hermits will not be able to. Finally, put in a bit of shrimp from your freezer, into the bottom of the glass.

This has worked for me a few times, including with a large (for my tank) black hitch-hiker.
