Killer Featherdusters?

[swimfree]

I have a type of featherduster that is invading some of my polyps. They wrap around each polyp and smother them.
I have many of these in my refugium and a few colonies on some small rocks. I have dipped the rocks, but the only thing that seems to work is pulling them off with tweezers. Does anyone know of a more effective/permanant way to control these?

Thank you.

These guys are good for the tank but have sen this. If they like a certian area then they will collect there. Mb try placeing the frag in another spot or just remove and fuge them.

I have heard a copperband butterfly fish will do the gob,I dont know if it is safe for a reef tank,more info is needed.

Sounds like a hydroid. Not a featherduster

Thank you all. I will research the hydroid.
