Green Hair Algae?

[CaptainsReef]

Is this green hair algae? If so, what do I do about it? This is the first time I've seen it and this is the only place I've seen it.

Looks to be a type of tube worm to me. Fan at the end of one stalk.

Does not look like hair to me. If it does have a fan you have a free gift. I would watch and see if it open at night or when you feed.

If it were hair, and only on something like that. I would just toss the rock/shell? If it were a crab/snail inside I would toothbrush it.

Are Tube Worms good or bad?

Good guys.

Tube worms are great. Fan worms even better. All my tube worms are white and seem to like to hang upside down in the rock caves. I do have a few brave ones that are out in the open on rocks.
