Emerald crab removal, best method?

[Holy_makerel]

My emerald crab has decided it enjoys eating SPS and i want to get it out without destroying my rockwork. Is there a trap i can make(or get) to help catch the little turd? Shell is approx 1.5" across. And what is best as bait?

Rest a glass up aginst a rock with some prawn in it , he goes in but can't get out , do this when the fish are sleeping lol , iv got a crab that I need out same thing was picking at the sps , trouble is I can't do this intill I get my cleaner shrimp out as he just nicks everything , might take awhile to get him but it works
Good luck getting him mate

Mine will eat lil pieces of shrimp pretty well if you could coax it out into the open that would be best
although if you feed it with tweezers I bet you could just pull it out while it's latched on to the shrimp

I've had good luck just snatching them out with a pair of tongs in the middle of the night.

Thank you for the replies. I'll try the glass and the tongs.

Take a small bottle with a mouth piece about the same width as the crab.... Then cut the top of like a funnel shape.
Flip the funnel you just made backward and place in into the bottle you just cut..so it kinda looks like a funnle in a bottle (also works with bees suprisingly) drop the shrimp or squid in the hole set it on its side and wait...the crab wont be able to get out...good luck

I just safety pinned a piece of krill inside a fish net, they walk right in and grab the krill and you can scoop it out without tearing the rockwork apart.
