strange yellow worms affecting Zoanthids?

[ahappel]

Hey guys,
I recently noticed that one of my Zoanthid colonies looks like it lost a few polyps. Somehow over time I didn't notice, you know how slow changes dont really get noticed? So not sure how long its taken but i'd say 3-weeks and lost about 6-8 polyps out of the 30.
Anyways There are some yellow stringy worm like things sticking out where the polyps are that seem irritated. I cant get a pic that shows the worms due to the coral's placement.

At first I thought they were spaghetti worms but aren't those supposed to be harmless? Th strings look like this: http://www.melevsreef.com/pics/05/11/spaghetti_worm3.jpg Just not in a big ball.

Any good way to get rid of them? I can remove the plug and do a dip, would a freshwater one be efficient or should i get some Iodine?

Parameters of water should be good as everything else seems happy.

FYI-
After some searching I discovered that some consider spaghetti worms "Zoa Irritators". I decided that this one fell into that category and pulled out the plug. Using some blunt but small forceps I dug around the crevices in the plug and pulled out an inch long fat yellow spaghetti worm! Hopefully that solves the issue.

Hopefully that works for you. Just sharing my experience: I have spaghetti worms all around many zoa colonies and they do not have any impact on them. It may be something else as well. Good luck.

They may irritate the polyps but that is it. They do clean up detritus that flows their way.
