Acropora austera is a beautiful small polyp stony (SPS) coral known for its delicate branching and vibrant hues, making it a prized addition to mature reef aquariums. Originating from tropical Indo-Pacific reefs, this species requires stable water parameters and expert care to flourish.
Care Requirements
- Lighting: High-intensity lighting such as metal halide, T5, or strong LED systems is essential to support photosynthesis and maintain vibrant colouration.
- Water Flow: Moderate to strong, turbulent water flow is recommended to prevent detritus accumulation and promote gas exchange.
- Placement: Position the frag in the upper to middle sections of the aquarium to ensure optimal light exposure and water movement.
- Spacing: Provide adequate spacing from neighbouring corals to prevent aggression and allow for healthy growth.
Additional Information
Acropora austera is considered a challenging coral best suited for experienced aquarists due to its sensitivity to water quality fluctuations. Regular monitoring of calcium, alkalinity, and magnesium levels is advised to support skeletal growth. This frag is reef safe with adequate spacing, making it compatible with a diverse reef community.
