The Acanthastrea pachysepta Splitcolour is a spectacular Large Polyp Stony (LPS) coral known for its striking bi-coloured polyps, making it a prized specimen for marine aquarium enthusiasts. This Extra Large variant offers a bold display of vibrant reds, greens, and oranges, adding a dramatic splash of colour to your reef tank.
Care Level: Moderate – best suited to aquarists with some experience in LPS coral husbandry.
Lighting Requirements: Moderate lighting is ideal, such as T5 fluorescents or LED systems with adjustable intensity. Avoid intense direct light to prevent bleaching.
Water Flow: Moderate, indirect water flow is recommended to ensure the coral’s polyps can extend fully without damage.
Placement: Position on the substrate or lower to mid-level rockwork, allowing ample space around it to prevent aggression with neighbouring corals.
Diet: While photosynthetic, Acanthastrea pachysepta benefits from supplemental feeding of meaty foods such as mysis shrimp or specialised coral foods 1-2 times per week.
Reef Compatibility: Yes, with adequate spacing. This coral can exhibit aggressive tendencies via sweeper tentacles, so maintain sufficient distance from other corals.
Origin: Not Provided.
Maximum Size: Up to 15 cm per colony head in captivity.
Minimum Tank Size: 90 litres (20 gallons) recommended to provide stable water parameters.
Regular water testing and stable parameters are essential for optimal health. Maintain calcium, alkalinity, and magnesium within reef-appropriate ranges to support skeletal growth.
