Pavona cactus | M

Pavona cactus is a fascinating large polyp stony (LPS) coral belonging to the Agariciidae family, prized for its distinctive cactus-like texture and vibrant appearance. This medium-sized specimen offers a unique addition to mature reef aquariums, providing both visual interest and moderate care demands.

Lighting Requirements: Pavona cactus thrives under moderate to high lighting conditions. LED, T5, or metal halide lighting systems are suitable, but acclimation to intense light should be gradual to prevent bleaching.

Water Flow: Moderate water flow is ideal to ensure adequate nutrient delivery while avoiding tissue damage. Too strong a current may cause stress, whereas too little flow can lead to sediment accumulation.

Placement: Position this coral on stable rockwork in mid to lower sections of the tank, allowing space for expansion. Maintain adequate spacing from neighbouring corals to prevent aggressive interactions, as Pavona cactus can exhibit territorial behaviour.

Care Level: This species is considered moderate in care difficulty, suitable for aquarists with some experience in maintaining LPS corals. Consistent water parameters and stable conditions are essential for healthy growth.

Diet: Pavona cactus benefits from supplemental feeding with planktonic foods such as phytoplankton, zooplankton, or specialised coral foods, although it derives much of its nutrition from photosynthetic symbionts (zooxanthellae).

Compatibility: Reef safe with caution; ensure adequate spacing to prevent coral warfare. Avoid placing near aggressive or fast-growing corals that may overshadow or damage it.

Origin and Size: Origin not provided. Medium size suitable for established reef tanks with a minimum volume of 75 litres (20 gallons) recommended.
