Acropora aculeus is a beautiful small polyp stony (SPS) coral known for its dense, bushy branching structure and vibrant colouration, making it a popular choice among experienced marine aquarists. This frag offers a manageable size for reef tanks and adds dynamic texture and movement to your coral display.
Lighting Requirements: This coral thrives under strong lighting conditions, ideally provided by high-quality LED, T5, or metal halide systems. Aim for an intensity that supports SPS corals, typically between 200-400 PAR.
Water Flow: Moderate to high water flow is essential to prevent detritus accumulation and to promote healthy polyp extension. Ensure turbulent, indirect flow to avoid tissue damage.
Placement: Position Acropora aculeus in the upper to middle regions of the tank where it can receive optimal light and water movement. Maintain adequate spacing from neighbouring corals to prevent aggressive interactions and allow for growth.
Care Level: This species is best suited to advanced hobbyists familiar with maintaining stable water parameters typical for SPS corals, including consistent alkalinity, calcium, and magnesium levels.
Water Parameters: Maintain temperature between 24-27°C, salinity at 1.025-1.026 SG, pH 8.1-8.4, and stable nutrient levels with low nitrates and phosphates.
Compatibility: Reef safe with adequate spacing; avoid placing near aggressive corals that may overgrow or sting it.
Regular monitoring and dosing of trace elements will support vibrant growth and colour retention. Frag format allows easy integration into existing SPS coral collections.
