Hydroid, Worm, aiptaisia in zoas

[NotReefsafe]

I have something in my zoas. At first I thought it was aiptasia and hit it with lemon juice, but now I think its something else. Maybe some kind of hydroid or feather duster? Some times its there, some times I don't see it, but it never changes location. Unfortunately this is the best pi2c I could get, as its tiny. Note I've dipped this colony twice since I got it 3-4 months ago, and removed a small white worm two weeks ago.

Hydroid or small feather duster.

If it’s a hydroid, remove with tweezers. If it’s a duster, it’s harmless. If not sure but it’s bothering your zoas, you can manually remove it

The one on the top left looks like a small feather duster, if so harmless.
The ones in the middle I can't make out. Need clearer pic.

The middle Is the same as the top. It seems to me like a hydroid...wouldn't removing allow them to reproduce?

If there’s a group they are likely hydroids. Not sure what you mean by removing them allows them to reproduce. Just make sure to remove the base as you pull them off. Easier to do it outside the tank if you can remove the rock.
