Edit: I see it now! I thought you were referring to the clove polyps and my post said as much. But then I zoomed in and saw the stuff growing up between the zoa polyps. So I edited and corrected myself.
Photos under white lights would still be helpful though.
Also, maybe the forks are below the Zoas. Some species of that dictators look drastically different. Some look quite similar. Maybe try spraying the Zoas with a turkey baster just enough to close them up and see if you can get a pic of what’s below?
