Description
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.
