hitchhikers - sea whip?

[advanwoerden]

Can anyone tell me what this is? Crappy pic I know, but they're all over my tank, in my rocks and sand. They look like tentacles, and seem to be harmless b/c they touch my coral and nothing happens. They shrink back when I make a sudden movement, and come out moreso at night, but otherwise just stay in one place swaying back and forth. They don't seem to be mobile, but the tentacle "feels" about on the rocks or sand wherever it can reach from where its attached. If you dont know what it is, do you at least know what eats it?

Definitely not sea whips. Sounds like some sort of worm but a better pic would help.

Sorry, I need to get a camera I know. I didn't see anything on that link fcamargo, but I don't think they are spionid worms. They look similar, but are a little bit "fuzzy". They look like they could be a worm, and are anchored to the rock/sand. They stretch out pretty long at night..
