Description
Scientific Name: Echinaster sp.
The color of the Orange Sea Star, or Starfish, may range from orange to red. It is sometimes called the Red Sea Star. It can have a variety of surface textures depending upon the locale. Some Echinaster Sea Stars have 6 arms.
It prefers a sandy, coral rubble substrate, or, especially live rock with algae. It moves over the surface, eating the small microbes and other bits of common detritus. A larger specimen could be harmful to clams, sponges, and small anemones in the reef aquarium.
The Orange 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.
In the aquarium, supplement with dried seaweed, and small pieces of clam meat, or tablets which can be placed under the starfish.
