The Mosaic Starfish originates from the reefs of the Indo-Pacific. The colour of this starfish is orange to tan and exhibits very distinctive colour patterns. The body of this star has many small circles, and is outlined with the pattern that follows into the legs. This outline creates another star shape which give a common name, Double Starfish. It is found over sandy substrates, on rocks and in crevices in the deeper parts of the reef. It is constantly foraging for micro-organisms and detritus to eat, so the aquarium should have ample amounts of live rock.
They generally lives alone, but if the aquarium is large enough to support more than one, it will tolerate others of its own species. The Mosaic Starfish is very intolerant of sudden changes in oxygen levels, salinity and pH of the water, and cannot tolerate copper-based medications. The drip acclimation method is highly recommended for all starfish due to their intolerability to changes in water chemistry. It should never be exposed to air while handling.
It is recommended to supplement its diet with small pieces of shrimp, mussel, or pellet food.
