hydroid or something else?

Hello, I have several of these whitish, transparent "worms" that extend and retract and hang out in the current. They do not seem to have a hard spiny base, they just extend directly out of the live rock. This one seems particularly irritating to the zoas. My son thinks they are hydroids. Hopefully not...

Look like hydroids to me.

+1 on the hydroids. Parma MI! I have done a few grids over there.

dang...are they going to cause a big problem, do I leave them be or try to get rid of them? If so, how do I do this?

Don't panic just yet.

I think they're "something else"... and a harmless something else at that. I just checked my reference books (where I recalled reading about these) but did not find anything there. I'll keep looking and will post whatever I find.

I've had these for years. Never more than a few here and there.
