Something in zoa frags

[Brassmonkey]

I have two zoa frags that have these things in them and think they might be feather dusters but I'm not sure and if they are are they harmful? I'll try to get shot of the other frag that is worse.
Thanks

They look like pinnated tenticals to me, so I'm guessing Xenia or Anthelia.

Really? A xenia. I have some in my tank but only put it there a couple months ago also it's on the other side of the tank but now that you say that it kinda looks like it. Any suggestions on what I should do?

I'd carefully scrap it off.
