This thing came on a rock of zoa's I got today. It kinda looks like an anemone. It did not close when I touched it, but it did close up when I put it in the reef dip before adding the rock to the tank. Any ideas on whether it is pest or not. And if it is pest how do I remove it?

i believe it is a rock anemone. another pest anemone. not near as prolific as mojano and aiptasia, but still an nuisance. kalk paste would prolly be a good thing to try first.
