Took me almost 2 years. Last hitchhiker from my live rock 2 years ago. Quite elusive. Would move frags around to use them to block in his cave, scraped live rock of coralline, scraped encrusting corals including acros. Mighta grabbed a small wrasse I had but unconfirmed. Just a royal pita. Tried tweezers, bottle traps, skewering him with a knitting needle. Nothing. Always got away. He was my Moby Dick and I was Capt. Ahab.
Last night, saw where he was at so decided to use the shot glass trap. Only problem is a shot glass would be too small for this guy. So went with a stemless wine glass. Dropped in a piece of shrimp and 30 secs later he was going for it. Not reckless though, very crafty. Tried reaching in with his legs still grabbing onto the rock and at one point I thought he might be able to reach it, but luckily the shrimp was just out of reach. He tried maybe 4-5 times of completely pulling out and then going back until finally he went all in and he couldn’t get out. Moved him downstairs to a frag tank where he can’t do anymore harm. JGT-1, hairy crab-0.
