My tailspot wrasse ate them too, however it wasn't until I exposed them that he decided they were tasty. I think the scrolling of the M. cap didn't allow him to get his fat head in there. Once I discovered that I indeed had them I wanted to take some photos so I broke a few pieces of cap off and flipped them over (nudis were on the underside) to get a shot of them. As I was focusing the camera the wrasse zoomed over and nipped them off the coral.
the moral of the story: if you're gonna try to get a wrasse to eat them, make sure its a small wrasse
