String of eggs of some sort?

So I wake up this mornin and I see this. It's hard to capture on camera but to describe it it's a white string popping out of my live rock. It looks like it's holding eggs in it. Is it good,bad,what is it? It just swings in the current. I don't think it's spaghetti worm.

P.s. It's in the center of the pic,coming out of the live rock.
