I have kept 100s of zoanthid colonies over the years....never seen it Mucho. Possible? Yep but I think they must taste nasty and/or have toxins.
Yeah, they are said to have a palytoxin (same as cowfish/boxfish/sea cucmbers etc) that makes tem undesirable to eat. I havent had any issues and i have kept them with a hippo tang in the past. I guess its on an individual by individual basis, some do some dont. I would put it past any species of hungry shrimp. My obese cleaner shrimp takes picks at them and irritates them (and me) closing their polyps in response. No probs with my current fish though.
