Little Worms irritating Zoanthids

[AquaReeferMan]

Hello everyone. Recently a decent size patch of some of my zoas have been closed. Upon closer view I noticed some small stringy worms around the area in which they were closed. They are about an inch long and very skinny. Any ideas on what the worms are and how to fix the problem. TIA

I doubt the worms are why your zoas are closed. They might be there to scavenge because the zoas in that patch are dying though. A pic of the worms would also help.
