Spirobid worms are they good? If not how to get rid of them?

Aiptaisia is fine I have file fish in my 20 gallon refugium from time to time I put the rock with aiptasia there and it takes care of them.

Zoas are not disturbed but here is another video my fear is that I have shrooms and a couple LPS if this thing spreads I am worried about other guys in the tank.

Doesn't really look like a spionid to me. Too many 'feelers'.

 

[therootcause]

Spirorbid worms, and I see some an aptasia in the first two seconds on the left hand of the video

I have never seen my spirobid worms extend a long tube like that.

Edit: Looked up Spionid...and that looks more like it.

Agree with above thought barnacle as well

 

[Qasim]

As long as they are not harming my corals they are fine to be there I will observe them closely to see if they do anything there.

It look like Chaetopterid/Spionid (Tube Worm). Easy you can check, when you see it out, to turn off the pumps and to see if the tentacles start to collect detritus from the surface, if then spinoid, if they stay up, then Pyrgomatid barnacle (but on the video t come out of a tube, which isn't normal for barnacle), and I don't see the small hair like on the tentacles which catch the food from the flow.
