Such free ranging crabs are not reef safe as all crabs are omnivores, meaning that it will happily eat any life on the rocks and if large enough, can also threaten coral polyps.

ok, thanks for info, can I catch the crab with same methods as a mantis shrimp, for example, with plastic bottle trap?

That might work, but it is easier or quicker if you remove the rock it is hiding within and force it out.
