Crab catching

[Viv]

Does anyone know of a way to catch a crab. It seems everytime I just about get the bugger, he slips into a crevice. I thinks he's eating the polyps from the base of my corals, he certainly is eating the flesh off the granulosa! (and I thought he was cute, and helping keep the corals clean)....

could you post a pic of the crab? most do not eat the flesh off of corals, unless the coral is dying.

have you tried the glass trick. sink a glass to the bottom. facing right side up. make sure the glass is taller than the crab is wide. put a small piece of food in the bottom. bury it up to the rim or put it next to the LR so the crab can get in. wait it out. once the crab falls in it should not be able to get out due to the glass sides.
