Anyone had any luck stopping spread of this unknown coral?

So I have this coral that I am not sure what it is (attaching pics). It must have been a hitchhiker because I didn't purchase it but it is literally growing wherever there is free rock space and in some cases over corals. I don't know how to get rid of it. Anyone know what it is and how to stop the spread of it and possibly get rid of it?

Maybe pom pom xenia? I would take out the rock, pass it forward to a new reefer

It looks like Xenia.

Does it pulsate

They are clove polyps, there’s a few threads on here were a febenzadole treatment was used to remove this pest.

I thought xenia at first but not sure, problem with removing the rock is it has basically gotten on every rock so it would be hard to remove the rock. I will check out the febenzadole treatment.

Looks like antheila to me, do not let it grow uninhibited
