THis is the first I have heard of zoanthids. Also note people jump to conclusions that this star is causing problems, often because it is in the wrong place at the wrong time. I participated in a thread where someone was certain it was eating their montipora because it was the only thing they saw, so they started removing them. Well upon closer look it was the montipora eating nudibranch that was causing the damage, and the star was just there. They WILL hang out in between zoanthids and such because they are feeding on surface films. There are some species that are KNOWN to eat SPS, one that someone produced a clear picture causing damage to a leather...and mostly causing damage to coralline algae.
They are also likely to eat corals that are dying for other reasons.
But there is a whole lot of the classic "mythinformation" out there about these. They will not SUDDENLY start eating them, they are either coral eaters, or not.
