I had for a short time, pulled 3-4 out in one week, one of which I saw chomping one my zoas, and I could see the zoa colonies suffering. I got a yellow coris wrasse and that took care of it. I had read that many wrasses of the haliochoeres family hunt nudibranch, and dwarf wrasses supposed to as well. Need a sand bed for haliochoeres, and if you have a small tank maybe a dwarf is better-I suggest reading up on these. Online research led me to choosing the yellow coris and it was always prowling the rock.
