The Red Knobbly Starfish have thick, grey body with multiple bright red tubercles extending upward along each of its five arms. Red stripes connect these protrusions, giving its back the appearance of wires interconnecting in a grid-like fashion. It is found in shallow tidal pools and up to 100' deep reefs in the Indian Ocean. The Red Knobbly Starfish requires a large aquarium with ample supplies of live rock. A small specimen will eat algae. As it grows older, however, it is not reef compatible, as it will eat soft corals, sponges, tubeworms, clams, starfish, and other invertebrates. It should not be housed with puffers.
They are very sensitive to high levels of copper-based medications and will not tolerate high levels of nitrates. The Red Knobbly 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. It should never be exposed to air while handling.
In the aquarium, the diet can consist of chopped clams, shrimp, fish, and squid fed once a week.
