The Acanthastrea pachysepta (Splitcolour) is a captivating large polyp stony (LPS) coral prized for its vibrant, contrasting colours and robust growth. This tiny-sized specimen is tank-bred, ensuring acclimatisation to captive conditions and promoting sustainable reefkeeping.
Belonging to the Mussidae family, this coral displays fleshy polyps with a distinctive split-colour pattern, making it a striking focal point in any reef aquarium. Its hardy nature makes it suitable for hobbyists with some experience in LPS coral care.
Care Requirements
- Lighting: Moderate lighting is ideal. LED or T5 lighting systems providing a PAR range of approximately 50-150 are recommended to maintain vibrant colours without causing bleaching.
- Water Flow: Moderate, indirect water flow helps keep the coral clean and healthy while preventing tissue damage.
- Placement: Position on the substrate or lower to middle areas of the rockwork to avoid excessive light and flow. Ensure adequate spacing from aggressive neighbours to prevent stinging or overgrowth.
- Water Parameters: Maintain stable marine conditions with temperature between 24-27°C, salinity at 1.023-1.025 SG, pH 8.1-8.4, and low nitrates and phosphates.
Compatibility and Reef Safety
This coral is reef safe with adequate spacing. It can coexist with other peaceful corals but requires room to expand its polyps without contact with more aggressive species.
Feeding
While photosynthetic, Acanthastrea pachysepta benefits from supplemental feeding. Offer meaty foods such as mysis shrimp, brine shrimp, or specialised coral foods 1-2 times per week to promote growth and vibrancy.
Additional Notes
Being tank-bred, this coral adapts well to aquarium life and supports sustainable marine aquaculture practices. Regular monitoring and stable water conditions will ensure long-term health and colour retention.
