I had one in my old reef years ago. This fish is really meant for picking out of crevices so they are more likely to eat worms and things like that. It is hit or miss for them to nip at the small aiptasia anemones. I would bet they are less likely to nip on bigger anemones.
Overall, they are pretty hard fish to keep.

Also, I would avoid eating these reef fish. Many reef fish are known to harbor toxic secondary metabolites from the sponges and other inverts they are eating. I wouldn't do it.
