Anyone know what these are?

My pistol shrimp moved this rock around and I noticed these tiny little heads of something growing. Any ideas?

Looks like either cloves or Anthellia xenia

Thanks for the quick reply's! It looked like Xenia to me as well but the Xenia in my tank opens and closes and these look abit different. Could it possibly be a some sort of hitch hiker?

Probably small pom poms or some clove coral is my bet.
