Dancing Worm ID! (short video)

They're not vermetid...the line they cast is moving around very deliberately, not swaying in the current. Whatever it is, it has prehensile control of the line. Also, the line has little fingers on it, it's not smooth and nearly invisible like vermetid. As you'd expect, whatever it is can retract the line all the way in. Any ideas? Seems to be really irritating that zoa colony--go figure :)

I'm following this thread as I have a good 10 or more in my mini reef... they stay in one spot tho... nowhere near my corals.
