Acropora spp. (Coral Sea) – Small are a popular choice among experienced reef aquarium enthusiasts. These small-sized Small Polyp Stony (SPS) corals originate from the Coral Sea and are prized for their intricate branching structures and vibrant colours.
Lighting Requirements: Acropora spp. thrive under strong, high-intensity lighting such as metal halide, T5, or high-output LED systems. Providing sufficient light is essential to support their symbiotic zooxanthellae and promote healthy growth.
Water Flow: Moderate to high water flow is recommended to ensure proper gas exchange, nutrient delivery, and to prevent detritus accumulation on the coral surface. Aim for turbulent, indirect flow rather than direct blasts.
Placement: Position these corals higher in the aquarium to maximise light exposure. Ensure adequate spacing from neighbouring corals to reduce aggression and allow room for growth.
Care Level: Due to their sensitivity to water parameters and lighting, Acropora spp. are best suited for advanced hobbyists with stable, mature reef systems.
Water Parameters: Maintain stable conditions with temperature between 24-27°C, salinity 1.025-1.026 SG, calcium 400-450 ppm, alkalinity 8-12 dKH, and magnesium 1250-1350 ppm.
Feeding: While primarily photosynthetic, Acropora spp. can benefit from supplemental feeding of planktonic foods such as phytoplankton or specialised coral feeds to support growth.
Origin: Coral Sea.
Maximum Size: Not Provided; growth depends on aquarium conditions.
