Duncan Coral? Or something else?

[maymay]

I friend gave me a mat of pink clove polyp which I put over a piece of rock. When I relocated the mat of clove polyps to a different tank I noticed something that I didn’t see before. Not sure what it is, almost looks like a small Duncan coral ?

Really hard to grab a good shot

Yep! Sure looks like a baby Duncan

Or green paly. Don’t see skeleton which Duncan would have.

In person it doesn’t look as green as the green palys online. There might be a small piece of skeleton attached the the rock at the foot, but really hard to tell. Guess I’ll find out when it grows. Any chance it is a pest ?

Definitely doesn’t look like a pest coral. Some are annoyed by certain Paly’s/zoa growth rates (Pandora) , so I would just keep an eye on it.

Thanks for the quick help!

A top down would help. It could be a pest nem... some mojanos look similar.

Ugh! It looks just like these. How bad of a pest is it? Remove immediately situation ? Or keep an eye on it?

I keep some in a nano tank for fun but they can multiply quickly and sting things.

You would eliminate the same way as aptasia.
Some reefers as tanberav stated do collect a couple until they get crazy in numbers. I personally dont keep any as I want tank pest free.

Good to know, I’ll be removing it since I plan to turn that setup into a frag tank.

And if it's Duncan, when you disturb it a bit more, it will retract to the level of the stone base-skeleton, then you will see is it duncan or Palythoa, or Majano like @Tamberav mention.
Can't say what's exactly at the moment, if you keep eye on it you will figure it out, if it start to spread faster, it's Majano, and you can take it off on time.

Yeah, dont think it is a Duncan. It doens't have a skeleton!

Calcium hydroxide (Kalk, Aiptasia X, etc.) applied thick and let sit for 30 minutes or longer with pumps off should do it.
