From LiveAquaria:

The Pipe Organ Coral is a soft coral, but is often referred to as a hard coral because of its red calcareous skeleton. Its common names may also include Organ Pipe Coral, or Daisy Coral. When its polyps are open, it is often confused with the star polyps or clove polyps because of their similar appearance. These corals do have the advantage over the other similar looking soft corals in that they will not spread across the rocks and crowd out other species.
