Sea Stars characteristically have five arms extending from a central disk like a star. In the aquarium they can be fed small pieces of fish, placing the food near or even under the Sea Star. Serpent and Brittle Sea Stars are popular additions to reef aquariums that contain live sand as they constantly stir the bed and provide oxygen to beneficial bacteria.
