how to catch a pistol shrimp

[bowkry]

I am a complete idiot, I shut down my biocude and put my pistol shrimp and gody into my main tank now the gody died (was killed) and I cant catch the pistol shrimp. I have tried every thing except ripping out all my rock, has anyone sucsessfully captured one without ripping out all the rock, and if they have a trap that worked can I borrow it?
