Please help ID a worm

[love my tank]

Unfortunately, I don't have a picture, but I have some sort of worm that comes out of a hole in a rock, it used to only come out in the dark, but I see it all the time now. It curls around the rock and the end of it is under some zoos that I have. It is a marled grey in color and what I guess is the head has a tiny fringe around it. It retracts into itself and disappears into the rock. It's definately not a feather duster as it doesn't have a shell. Any ideas????

Google... peanut worm
Be my guess with no picture and your description... any others comment on it?

I think that's it. How crazy. I'm amazed how these things just "appear". I'm glad it's harmless. Thanks for the quick reply!!!

I'll have to google the spaghetti worm....the "peanut worm" used to only come out at night and if I shined a flashlight on him he would scurry back in his hole, but lately he is out all the time. He's kinda interesting to watch.
