Briareum

Briareum is a genus of soft corals in the family Briareidae. The coral is cultivated by aquarium owners (under the common name "green star polyp" or GSP) for its fluorescing polyps, which reveal themselves under actinic light. The genus is in need of extensive examination, as many specimens sold by marketers display unique and similar characteristics, but are often labeled as one species, Pachyclavularia violacea.
