Red Knob Starfish (Protoreaster linckii)

The Red knobbed Starfish is also known as the African Sea Star. This star requires an aquarium of at least 30 gallons with plenty of rocks. It can grow up to 8 inches. This star when small eats algae. When they are large in size they will eat sponges, corals, tubeworms, clams, starfish, and other inverts. This star is not considered reef safe. Avoid putting this star with Puffer fish. Like other stars they are very sensitive to copper based medications.
