Put them in a strawberry basket or the like suspended in the tank, or in a breeder box. They're not likely to be the problem- go make a post in, maybe the disease forum? List tank size, tank age, water parameters (in numbers, not just "good"), tank inhabitants, and anything that comes to mind.

Thank you for the informative feedback. Sorry new here don’t really know where to post certain situations have a hard time even posting anything. I believe it was the emerald crabs , since I bought them I have lost a blood shrimp, fire fish , neon dottyback , as well as a mandarin goby witch all where fine before that . Do weekly water changes, 10% have my ph at 8.3 and salinity at 2.025 ammonia, nitrate ,nitrite at 0. The two fishes (fire fish / neon dotty back) missing have disappeared completely my mandarin had what looked like a gouged in its top dorsal fin . Also noticed all fish tend to sleep at the bottom of the aquarium. No diseases in my tank .

Is there any algae in the tank for the crabs to eat, and are you sure they're emerald crabs? That does sound like a crab problem.

You also have a different problem, though less urgent; your nitrates are too low. You should have at least 5ppm. Reduce water changes to bring those up, or you'll wind up starving your beneficial algae and any corals you may have.

I don't know about /can't/, they do have those claws. It'd be difficult, but if one was hungry enough, got lucky, and got ahold of a fish, that could be a problem.
The claws are for show, ie: attracting the opposite sex. I've had numerous emerald large crabs and they've had ample opportunity to pick off much smaller fish - but aside from occasionally waving their claws around they seem to be most content scrounging for morsels amongst the corals.

As @Spare time indicated, they can't kill a healthy fish. I don't know what kind of fish we're talking about either (9 times out of 10 they're hiding, in the overflow/sump or on the floor somewhere).

ive had emerald attack and kill healthy fish, usually at night if they sleep in the small crevices. Had to rescue a hippo tang once and most recenntly a small 6 line. They eat what they can get their lil claws on
