Protoreaster nodosus, often called the horned sea star, is a visually impressive marine invertebrate prized by aquarium enthusiasts. Known for its distinctive knobby arms and robust body, this starfish adds a unique dimension to reef tanks and marine setups.
Care Level: Moderate care is required to maintain healthy Protoreaster nodosus specimens. They are sensitive to water quality and require stable marine conditions.
Feeding: This species is primarily a scavenger and detritivore, feeding on leftover food, detritus, and biofilm. Supplementary feeding with meaty foods such as chopped molluscs or marine pellets is recommended to ensure nutritional balance.
Compatibility and Reef Safety: Protoreaster nodosus is generally reef safe and compatible with a wide range of peaceful tank mates. However, caution is advised as some starfish may prey on slow-moving or sessile invertebrates. Monitor interactions closely.
Tank Requirements: A minimum tank size of 75 litres is recommended to provide adequate space and stable water parameters. Moderate water flow and low to moderate lighting conditions are ideal, mimicking their natural habitat.
Placement: Place the starfish on sandy or fine rubble substrate where it can forage naturally. Avoid placing near aggressive or predatory species.
Origin: Not Provided.
Maximum Size: Typically grows up to 30 cm in diameter.
