Green Stuff....

They look like a type of star polyps to me, I have 3 types in my tank, it will typically spread steadily around bare rock, up the side of the tank or wherever - looks like grass and "blows to and fro" in the flow of water, a great addition to any reef - easily kept as long as your nitrates and phosphates are under control.
They are a two part coral, like a pink fleshy base which spreads and then is hosted by a bacterial parasite which then brings the grassy appearance. And yes, fraggable !!!!!!!!!!!!!

looks like green star polyps. They grow wicked fast but they really do look nice
