I hate crabs

[Twinn]

This is the dude that is causing me sleepless nights. Can't seem to catch him to save my life and the crab is too smart to fall for the old bottle trick. Guessing by the size of the huge pinchers he isn't a good crab to have in the tank. Any ideas how to get the crab out. The thing is fast sorry about the bad pic.

if you can get to the crevice he lives.
fill a syringe with acid (vinegar or hydrochloric or muriatic) and give a good squirt in there make sure you are not near any corals.

Or take the rock out and pry him out with tweezers.
good luch or luck.
