The Acanthastrea pachysepta (Splitcolour) is a spectacular large polyp stony (LPS) coral from the Mussidae family, renowned for its striking split-colour polyps that add vivid contrast and texture to reef tanks. This coral is a prized specimen for marine aquarists looking to enhance their display with bold, colourful corals.
Care Level: Moderate – best suited for aquarists with some experience in LPS coral husbandry.
Lighting Requirements: Moderate lighting is ideal. LED or T5 lighting systems that provide a balanced spectrum will support healthy growth without causing bleaching.
Water Flow: Moderate, indirect water flow is recommended to ensure the coral’s polyps can extend fully without being damaged by strong currents.
Placement: Position this coral on the substrate or lower to middle areas of the tank where it can receive moderate light and flow. Ensure adequate spacing from neighbouring corals to prevent aggressive interactions, as Acanthastrea species possess sweeper tentacles.
Diet: While photosynthetic, this coral benefits from supplemental feeding of meaty foods such as mysis shrimp, brine shrimp, or specialised coral foods to promote vibrant colours and growth.
Reef Compatibility: Yes, with adequate spacing. Care should be taken to avoid placing too close to other corals due to potential aggression.
Origin: Not Provided.
Maximum Size: Large colonies can reach up to 15 cm or more in diameter under optimal conditions.
Minimum Tank Size: 90 litres (approximately 20 gallons) recommended to provide stable water parameters and space for growth.
Regular water quality monitoring and stable parameters are essential for maintaining the health and vibrancy of this coral. Ideal water parameters include temperature 24-26°C, salinity 1.023-1.025, calcium 400-450 ppm, alkalinity 8-12 dKH, and magnesium 1250-1350 ppm.
