The Biscuit Starfish has an orange to tan colour, while its arms have cream-coloured spots. It is found over sandy substrates, on rocks, and sometimes climbing on anemones. It is constantly foraging for micro-organisms and detritus to eat, so the aquarium should have ample amounts of live rock. It generally lives alone, but if the aquarium is large enough to support more than one, it will tolerate others of its own species.
The Biscuit Starfish 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 Starfish due to their intolerability to changes in water chemistry.
They should never be exposed to air while handling. It is recommended to supplement its diet with small pieces of shrimp, mussel, or pellet food.
