Acropora millepora (Rainbow) is a stunning small-sized SPS coral prized for its vivid, multicoloured branches that add dynamic visual interest to mature reef aquariums. This species requires stable, high-quality water conditions and is best suited to experienced hobbyists.
Lighting: High-intensity lighting such as metal halide, T5, or high-output LEDs is essential to support photosynthesis and vibrant pigmentation.
Water Flow: Moderate to strong, turbulent water flow is recommended to prevent detritus accumulation and promote healthy polyp extension.
Placement: Position this coral in the upper to middle regions of the tank where it can receive ample light and water movement. Ensure adequate spacing from neighbouring corals to avoid aggression and tissue damage.
Care Tips: Maintain stable water parameters with low nutrients, including calcium (400-450 ppm), alkalinity (8-12 dKH), and magnesium (1250-1350 ppm). Regular water changes and consistent monitoring are vital for optimal health.
With proper husbandry, Acropora millepora (Rainbow) will flourish, showcasing its spectacular colours and intricate branching structure.
