Pavona cactus is a visually striking large polyp stony (LPS) coral from the Agariciidae family, prized for its unique cactus-like growth form and textured surface. This small specimen is perfect for hobbyists looking to add an interesting and hardy coral to their reef aquarium.
Lighting Requirements: Pavona cactus thrives under moderate lighting conditions. LED or T5 lighting systems providing a PAR range of approximately 100-200 µmol/m²/s are ideal to maintain healthy growth and vibrant colours.
Water Flow: Moderate, indirect water flow is recommended to ensure adequate nutrient exchange without causing tissue damage. Avoid placing the coral in direct strong currents.
Placement: Position Pavona cactus on stable rockwork with sufficient space from neighbouring corals to prevent aggressive interactions. It is best placed mid-level in the tank where lighting and flow conditions are optimal.
Care Level: This species is considered moderate in care requirements, suitable for aquarists with some experience in maintaining LPS corals.
Diet: Pavona cactus benefits from supplemental feeding of small meaty foods such as mysis shrimp or specialised coral foods, although it derives much of its nutrition from photosynthesis via its symbiotic zooxanthellae.
Reef Compatibility: Yes, with adequate spacing. Pavona cactus can exhibit aggressive behaviour through sweeper tentacles, so ensure it is not placed too close to other corals.
Origin: Not Provided.
Maximum Size: Typically grows up to 15 cm in diameter under optimal conditions.
Minimum Tank Size: A minimum tank size of 75 litres (20 gallons) is recommended to provide stable water parameters and adequate space.
Regular monitoring of water parameters, including calcium, alkalinity, and magnesium, is essential to support skeletal growth. Maintain stable temperature (24-26°C), salinity (1.023-1.025 SG), and low nutrient levels for best results.
