Marie,

From wetwebmedia:

"Pachyclavularia violacea. Indo-Pacific. Grow as thick mats that may cover meters of bottom. Stolon has purple reddish color to which all polyps are joined. Photosynthetic. May grow quickly in your aquarium, crowding out desired livestock. Best to confine to individual rocks with a break in-between. Middle of polyps white to greenish, tentacles brownish to greenish. Pinnules on tentacles very small."

It's some sub-species of star polyps.
