The Acanthastrea echinata (Ultra) is an impressive Large Polyp Stony (LPS) coral prized for its vivid colours and bold polyp structure. This Extra Large specimen offers a dramatic focal point for mature reef aquariums, showcasing the characteristic fleshy polyps and intricate skeletal formations typical of the Mussidae family.
Lighting: Moderate to low lighting is recommended to prevent bleaching and maintain vibrant pigmentation. LED or T5 lighting systems with adjustable intensity work well.
Water Flow: Provide low to moderate, indirect water flow to ensure adequate nutrient delivery without damaging the delicate polyps.
Placement: Position this coral on the substrate or lower rockwork where it can expand fully without competition. Maintain adequate spacing from neighbouring corals to avoid aggressive interactions.
Care Level: Suitable for intermediate to advanced hobbyists due to its size and specific husbandry needs.
Diet: While photosynthetic, Acanthastrea echinata benefits from supplemental feeding of meaty foods such as mysis shrimp, brine shrimp, or specialised coral foods 1-2 times per week.
Compatibility: Reef safe with caution; ensure sufficient space to prevent stinging or overgrowth of nearby corals.
Regular water parameter monitoring and stable conditions are essential for optimal health and growth. This coral thrives in well-established marine aquariums with stable salinity, temperature, and nutrient levels.
