Button Polyps killing my corals

No, I know that. I kalk those sucker quickly if they show up !

 

Now you guys have me worried. I thought i had aptasia but when i posted a picture i was told they were harmless button polyps.
I've got them on a rock of Zoos and they started out as one, but now there's like 4 or 5.

Should i get rid of them or what?

 

I have some on an individual rock which I will keep. Just away from the other rocks. Just keep an eye on them, they multiply quickly. If it was me I'd prefer the zoo's and get rid of polyps while you can if they are on the same rock.

I scraped off all I could tonight in a seperate bowl, but they are so deep into the skeleton that I can't get it all. I figured that I could kalk them now when a head would pop up. Maybe the brain will have a chance to take off now. Chemical warfare is happening in my tank now so I'm glad I got carbon !
