The Acanthastrea pachysepta Splitcolour is a spectacular large polyp stony (LPS) coral prized for its striking dual-colour polyps that add vivid contrast and texture to any marine aquarium. This XXXL specimen offers a commanding presence, perfect as a focal point in mature reef systems.
Care Level: Moderate – suitable for aquarists with some experience in LPS coral husbandry.
Lighting Requirements: Moderate lighting is ideal, such as T5 fluorescents or LED setups providing PAR levels between 50-150. Avoid intense direct light to prevent bleaching.
Water Flow: Moderate, indirect water movement is best to ensure polyps can extend fully without stress from strong currents.
Placement: Position on the substrate or lower to middle areas of the tank where lighting and flow conditions are stable. Ensure adequate spacing from neighbouring corals to prevent aggressive interactions.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from occasional feeding of meaty foods such as mysis shrimp, brine shrimp, or specialised coral foods to promote growth and vibrancy.
Reef Compatibility: Yes, with adequate spacing. This coral can extend sweeper tentacles and may sting nearby corals if placed too close.
Origin: Not Provided.
Maximum Size: Can grow to approximately 15-20 cm in diameter under optimal conditions.
Minimum Tank Size: Recommended for tanks 90 litres (approximately 24 US gallons) or larger to provide stable water parameters and space.
Regular water quality monitoring and stable parameters are essential for long-term health. Maintain temperature between 24-27°C, salinity at 1.023-1.025 SG, and stable alkalinity and calcium levels.
