Peppermint predator?

[spawn]

I want to get them out because they've developed a taste for My seriatopora/yellow tipped birdsnest. This is the second time starting to lose this type of coral, but the first time that I'm aware of the cause since I witnessed the shrimp eating it. I would prefer to get rid of them manually, however doing so is not without it's challenges, I've got alot of sps frags that are happily planted and staring growth that I don't want to jeopardize by trying to catch a shrimp.
