digitate hydroids?

How old is your tank? I have searched both on here and RC looking at old threads on these guys. From what I read they tend to go away in time. They will let go of the rock to go to another spot as well and there was one suggestion to filter the water to catch them as they release. I have a lot of them in my tank right now and it is a new tank. My Zoa has not seemed to be bothered by them yet. I am hoping to give it a year and let them die off naturally.
