what is this worm? Parasite?

[c_scherer123]

I got some corals recently (my first - I am new at reefing) and the mushrooms have been slightly curled since I got them. I thought my lighting was too strong and moved them into the shade. Tonight I noticed several white, curly worms on the underside of the mushroom cap. (posted links as I consider to picts too large to post without bothering people with 800x600 screen settings).
What are they and how do I get rid of them? They are worms right? They are attached pretty well as I tried to remove one to get a closer shot (and failed...).

My water is testing in at near perfect levels, I tested because when something looks out of whack I immediately suspect the water quality.
