The Double Sea Star (Icon Sea Star) is a species of starfish native to the reefs of the Indo-Pacific, with an orange-to-tan color and a very distinct pattern of circles and outlines. This unique pattern is the origin of its common name, as it creates the impression of two stars. The Double Sea Star is a unique and impressive species and a fantastic addition to any reef or aquarium. It is also known to be a hardy species and easy to care for, making it a great choice for aquarists of all levels of experience.

This species, commonly known as the Blackcap Basslet, is a hardy and relatively easy to care for fish. It is a peaceful omnivore, meaning it eats both meaty foods and vegetation. It is found over sandy substrates, on rocks and in crevices in the deeper parts of the reef. In addition, it is also found in shallow waters and coral reefs. It is constantly foraging for micro-organisms and detritus to eat, so the aquarium should have ample amounts of live rock to provide the necessary nutrients. Furthermore, it is important to ensure that the aquarium is large enough to support more than one, as this species generally lives alone, but it will tolerate others of its own species.

The Double Sea Star is a very sensitive fish and is not recommended for those with a low tolerance for changes in water chemistry. The drip acclimation method should be used with all Sea Stars due to their intolerance to sudden changes in water conditions. It should never be exposed to air while handling.
