Acropora granulosa is a stunning small-polyped stony (SPS) coral known for its fine, granular texture and elegant branching structure. This tiny variant is perfect for hobbyists with established reef tanks looking to add a delicate and visually striking coral specimen.
Lighting Requirements: Acropora granulosa thrives under high-intensity lighting such as metal halide, T5, or strong LED systems. Aim for PAR levels between 250-400 µmol/m²/s to support healthy growth and vibrant coloration.
Water Flow: Provide strong, turbulent water flow to mimic natural reef conditions. This helps prevent detritus accumulation and supports coral respiration and nutrient exchange.
Placement: Position this coral higher in the aquarium to ensure adequate light exposure. Maintain sufficient spacing from neighbouring corals to avoid aggression and allow for growth.
Care Level: Due to its sensitivity, Acropora granulosa is recommended for intermediate to advanced aquarists. Stable water parameters, including calcium (400-450 ppm), alkalinity (8-12 dKH), and magnesium (1250-1350 ppm), are essential.
Reef Compatibility: Yes, with adequate spacing. This coral is generally reef safe but may engage in chemical warfare if placed too close to other corals.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from occasional feeding of fine particulate foods such as coral-specific amino acids or plankton supplements.
Origin: Not Provided.
Maximum Size: Typically grows up to 10-15 cm in branching diameter under optimal conditions.
Minimum Tank Size: A minimum of 90 litres (20 gallons) is recommended to maintain stable water quality and adequate space.
