Help!! Aptasia or something else??…

[FOliveira]

Hi guys,
Recently started my first saltwater tank, and having difficulty identifying what pest this is. I assumed aptasia but looks different from the aptasia pictures I see online, it’s thinner and has small balls/heads at the end of each little thread… I introduced some Berghia nudibranches yesterday, thinking it was aptasia, and they do not look very interested so far.
Can you please help me identify what this is, and how to remove it?
Thank you so much!

It’s not Aiptasia, looks like hydroids.

Piggybacking on this for help ID’ing … looks very similar to what I have.

I had this a while ago on my zoas too. I dipped for the max amount of time with Reef Dip and it went away in a couple days
