The Picaso Starfish has long cylindrical arms that are red in colouration. This starfish is one of the most popular with reef enthusiasts and thrives when maintained in good water conditions. A very active starfish, this species is normally visible during the day. It prefers a well-lit aquarium with a sandy, coral rubble substrate, and live rock. It will move over the rock searching for small microorganisms and other bits of common detritus to eat.
They may be harmful to clams, sponges, and small anemones. The Picasso Starfish is generally solitary. It is very intolerant of sudden changes in temperature, oxygen levels, salinity and pH of the water, and cannot tolerate copper-based medications. It should never be exposed to air while handling.
In the aquarium, the diet should be supplemented with dried seaweed, and small pieces of clam meat or pellets can be placed under the star.
