I never seen a wrasse eat a coral. Only spit sand on them. I know the cbb and foxy may enjoy them. Mine would pick on the ones with the long lashes and eventually figured out they were not aiptasia. She no longer cares for them. Foxy got a new home. I was ticks seeing 70 utter chaos get eaten.Man, it’s a pain how the foxes are beautiful but they can really turn. I avoid Zoas as something in my tank picks them, the issue is I can’t rule it down to the foxface as I also have a CBB and several wrasses. Although I doubt the wrasses would go after the coral.
