Acropora (Acropora spp.)
Acropora are among the most iconic and highly prized small polyp stony (SPS) corals in the reef-keeping hobby. Known for their branching, tabling and staghorn growth forms, they create intricate, three-dimensional structures that add height, depth and natural reef character to advanced marine aquariums.
 
Colour & Appearance
Available in a vast range of colours, including vibrant blues, neon greens, deep purples, pinks and multi-tone combinations, Acropora species are celebrated for their intense pigmentation. Under high-intensity reef lighting, particularly strong blue spectrum, their fluorescence becomes even more pronounced, producing striking visual impact.
Placement & Flow Requirements
Acropora thrive under high-intensity lighting and strong, turbulent water flow.
Best positioned in the upper areas of the aquarium for optimal light exposure.
Provide varied, random flow to promote healthy tissue, strong skeletal growth and full polyp extension.
 
Care Level & Compatibility
Generally best suited to experienced reef keepers, Acropora require stable, mature systems with consistent water chemistry. When maintained correctly, they grow steadily and can become dominant structural centrepieces within SPS-dominated displays.
 
Water Parameters
Temperature: 24–26°C

Summary
Acropora corals represent the pinnacle of SPS reef keeping, offering rapid growth, intricate form and exceptional colour for well-established marine aquariums.
