Symphyllia (Australophyllia) wilsoni (Ultra) Large is a captivating large polyp stony (LPS) coral prized for its striking colours and distinctive fleshy polyps. Belonging to the Mussidae family, this coral is a spectacular addition to mature reef aquariums, offering both visual appeal and moderate care requirements.
Care Level
Moderate care level; suitable for aquarists with some experience in maintaining LPS corals.
Lighting Requirements
Prefers moderate lighting conditions. LED or T5 lighting systems that provide a balanced spectrum are ideal. Avoid intense direct light to prevent bleaching.
Water Flow
Moderate, indirect water flow is recommended to ensure proper gas exchange and to prevent tissue damage from strong currents.
Placement
Position in the lower to middle regions of the aquarium where lighting and flow conditions are stable. Ensure adequate spacing from neighbouring corals to prevent aggressive interactions, as Symphyllia (Australophyllia) wilsoni can extend sweeper tentacles.
Diet
Primarily photosynthetic but benefits from supplemental feeding of meaty foods such as mysis shrimp, brine shrimp, or specialised coral foods 1-2 times per week.
Reef Compatibility
Yes, with adequate spacing from other corals to avoid aggression.
Minimum Tank Size
Recommended minimum tank size is 90 litres (approximately 20 gallons) to provide stable water parameters and sufficient space.
Additional Husbandry Notes
Maintain stable water parameters with temperature around 24-26°C, salinity at 1.023-1.025 SG, and low nutrient levels. Regular water changes and monitoring of calcium, alkalinity, and magnesium are essential for skeletal growth.
