Do I remove it or what should I do?

I would remove it since it's invasive to rocks and will irritate zoas. But it is generally a good sign of a reef tank's maturity.

You can dip the zoa in peroxide and tank water mix and use a baster to blow it off the rock. Otherwise, in case you cant dip, just peel it off with tweezers or blow it off with a baster in tank.

Can you take a turkey baster and blow it off the Zoas? What would happen if you did?
