Acanthaster planci | M

Acanthaster planci, commonly known as the Crown-of-Thorns Starfish, is a striking marine invertebrate known for its distinctive spiny appearance. This medium-sized specimen is best suited for experienced marine aquarists due to its specialised care requirements and diet.

Feeding: This species primarily feeds on coral polyps, which can make it unsuitable for reef tanks containing live corals. In captivity, feeding can be challenging; some aquarists offer alternative foods such as soft coral substitutes or specialised coral-based diets, but success varies. Regular monitoring is essential to prevent damage to live corals.

Compatibility and Reef Safety: Due to its coral-eating habits, Acanthaster planci is generally considered Not Reef Safe. It should be housed in dedicated systems or with caution in mixed reef setups. It is compatible with other non-coral-eating invertebrates but should be kept away from delicate coral species.

Tank Requirements: A minimum tank size of 150 litres is recommended to provide adequate space and stable water conditions. Moderate water flow and stable water parameters are essential for its health. Placement should allow the starfish to move freely without risk of injury.

Care Level: Advanced. This species requires specialised knowledge and commitment to maintain in captivity.
