Worms

[gw82]

I have these long skinny white worms that are all over some of the rocks. They have fanlike tentacles at the end that are pinkish hue. Can anybody ID them? I saw one from behind a rock and actually thought aptasia. I think they're prob beneficial filtering hitchhikers but wanted some experts to weigh in. Thanks
