Depending on how big he is, can't hurt to try

Are you going to confirm it's the blenny before you yank it out ?
A red light, or a flashlight shone through your fingers works well

He's the only one active at night when the corals get bit. I've seen him take a little bite of one of my montis and the bit makes look consistent with the bite marks made in the algae on my glass... So fairly confident.
