The Starburst Polyps are also referred to as Star, Eight Tentacle, Mat, or Daisy Polyps. They are usually white or brown with a white dot in the center of each polyp, although, some more rare Starburst Polyps are green. The green specimens have been called Clavularia viridis; however, they are now identified as a Briareium sp. They have the distinctive eight-leaved tentacles on each polyp. They are colonial animals with several individual polyps attached to a piece of live rock.
Accurately described as an encrusting coral, Starburst Polyps rapidly grow over adjacent rock work, coral, or even the glass of an established reef aquarium. They are a peaceful coral armed with the defensive capability of being able to retract or deflate each of their polyps in response to predation. They will not harm other corals that are placed close to their colony, but are susceptible to being damaged by any aggressive corals in the reef aquarium. They are easy to maintain in the reef aquarium and make an excellent candidate for the beginning through expert reef aquarist. They require a medium to high light level combined with a medium to strong water movement within the aquarium. For continued good health, they will also require the addition of iodine and other trace elements to the water.
