What's on my Zoas?

[TwiTch18]

Howdy,
Just wondering if anyone knows what is on my Zoas?

I noticed them a couple of weeks ago but they are very apparent after returning from vacation.
It looks like some type of coral or hydra but I'm really not sure.
I worry it will choke my Zoas to death. They are just starting to get comfortable with the new tank.

Any advice or information would be amazing!
Thanks in advance

Cheers.

Looks like blue clove polyps. They can be very invasive.

Oh yeah, totally looks similar. Would they kill back Zoas? lots of stuff seems resistant to them

Ya id scrub those off with a toothbrush if possible.

How will the Zoas do with that?

Agree with @cpoynter - blue clove polyps. They're a nightmare. Will overtake most corals and almost impossible to kill. If you're able to scrape them off keep the plug isolated and watch to make sure they don't come back.
