Iconaster Longimanus - Double Sea Star

The Double Sea Star, also known as the Icon Sea Star, originates from the reefs of the Indo-Pacific. The color of this star is orange to tan and exhibits very distinctive color 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 its common name, Double Sea Star, originates from.

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. It generally lives alone, but if the aquarium is large enough to support more than one, it will tolerate others of its own species.

The Double Sea Star 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 Sea Stars due to their intolerability to changes in water chemistry. It should never be exposed to air while handling.

It is extremely difficult to breed in an aquarium, with no distinguishing characteristics to help differentiate it from its mate.

It is recommended to supplement its diet with small pieces of shrimp, mussel, or flaked food.
