Feather Duster or Tube Worm

[220Gallon-Tim]

Hey everyone, I have the follow growing in my tank like wildfire. I assume its not good because of the quantity I now see in the tank. Worms or feather dusters??? How can I get rid of them?

They look like feather duster tubes of some sort. I wouldn't worry about them. They don't appear to be vermetids or anything like that.

Yeah, look like Sabella. They will come and go depending on level of nutrients/food. If you don't want them send them to me - add diversity and interest imho.
