Acanthaster planci | L

Acanthaster planci, commonly known as the Crown-of-Thorns Starfish, is a large, spiny starfish native to Indo-Pacific coral reefs. This species is notable for its multiple arms and venomous spines, making it a fascinating but challenging addition to a marine aquarium.

Care Level: Due to its specialised feeding habits and potential impact on coral reefs, Acanthaster planci is recommended for advanced hobbyists only.

Feeding: This starfish primarily preys on live coral polyps, which means it requires a reef environment with abundant coral or supplemental feeding with coral-based diets. It is not suitable for reef tanks where coral preservation is a priority.

Compatibility and Reef Safety: Acanthaster planci is not reef safe as it feeds on live corals and can cause significant damage to reef systems. It should be kept in species-specific or coral-free systems to prevent coral loss.

Tank Requirements: A minimum tank size of 180 litres is recommended to provide adequate space and stable water conditions. Moderate to strong water flow is preferred to mimic natural reef currents, and lighting should be moderate to support coral growth if present.

Placement: Place the starfish on stable rockwork or substrate where it can move freely and access food sources. Avoid placing it near delicate or prized corals unless feeding is carefully managed.

Special Considerations: Handle with care due to venomous spines that can cause painful stings. Use gloves and avoid direct contact. Monitor coral health closely if kept in mixed reef tanks.
