Our Metallic Green Galaxea Coral is a popular large polyp stony (LPS) coral that many reef enthusiasts have or want in their collection. The Galaxea genus is easy to care for. Its polyps resemble a star burst and are tipped in white, give it a sparkling crystal-like appearance. The tentacles have a mesmerizing movement to them as they undulate in the aquarium. Common names it is known by, reflecting some of those great characteristics, are the Star Coral, Crystal Coral, Brittle Coral, Starburst Coral, Scapel Coral, and Durian Coral.
Difficulty It is easy to maintain in the reef aquarium, which makes it an excellent candidate for the beginning through expert reef aquarist.
Aggressiveness Though not as aggressive as wild colonies, prove a good amount of space between it and other corals to prevent its sweeper tentacles from damaging them, and for its own growth needs.
Requires low to moderate water movement.
Provide the Galaxy Coral with good light. T5's, Metal Halides, or LED's can all grow Tongue Coral when the proper levels are provided. We recommend a 14-20K color spectrum for best coloration.
A well-feed live rock/reef environment is what is needed for Galaxy Coral , along with some fish for organic matter production.
Diet and Feeding
In captivity, filter feeding/invert food should be offered as well as tiny bits of shrimp and fish. Aquacultured Metallic Green Galaxy Coral can be fed small zooplankton, adult or baby enriched brine shrimp, mysis, or similarly sized food. Feed a few times a week.
The G. fascicularis has been propagated in captivity. Propagation has occurred in aquariums by fragmentation. To propagate, use a wire saw blade and cut into even segments. These segments will easily encrust, and they can also be suspended by a string or plastic wire, keeping the coral from touching any surrounding surfaces.
