PYRO,
actually those are two different types of GSP one has green centers and the other has green tenticles. and no i don't try to spread them actually they are issolated so they can't spread off the current rocks and take over the whole tank.
WHO DEY,
i wouldn't be mad if your "meat coral" doesn't look like that. i think the term " meat coral" came about because people just needed a broad term to call this species of coral. i believe there are several very diiferent types of coral that fit under this broad title. all i can suggest is take a picture and as the boards for an ID. someone will give a sure answer.
HTH
