No Ruth, I haven't managed to kill any of the little buggers. I have two rocks that I think are covered with them. One rock is exactly like the photo I posted, the other rock sort of looks like maybe anthelia is starting on it, the "stems" aren't as thick and they only have 5 "rough" tentacles that remind me of anthelia. I'm actually thinking about taking both rocks out and boiling them.

BTW, you can get GSP off rock pretty easily, they sort of peel off in sections, just start it with a sharp knife. At least you could recoup some of them. Make sure they don't have any hydroids mixed in though.
