Description
The Red Knob Star (Protoreaster nodosus) is an eye-catching marine invertebrate known for its vibrant red or orange color and unique knob-like projections on its arms. This starfish adds a striking visual element to reef aquariums and is admired by aquarists for its stunning appearance.
With a peaceful temperament, the Red Knob Star is compatible with a variety of tankmates, including fish and other invertebrates. It does not pose a threat to coral or other aquarium inhabitants, making it a suitable choice for community setups.
As an omnivore, the Red Knob Star primarily feeds on detritus, algae, and small organisms found on the substrate. In captivity, it is essential to provide a varied diet that includes high-quality marine pellets, frozen food, and other nutritious options to ensure its health and vitality.
Red Knob Stars prefer stable water conditions and should be housed in a minimum tank size of 50 gallons to accommodate their potential size. Providing plenty of hiding spots and a well-structured environment will help them thrive in a captive setting.
