Introduction to Acropora Acropora corals are the centerpiece of many advanced reef systems, boasting an incredible variety of species such as Acropora tenuis (Tenuis), Acropora formosa (Stag), Acropora millepora (Millie), and many more. Each species offers its own unique growth patterns, colors, and textures, with some of the most vibrant coloration found in the reefing world. While they require careful attention and stable tank conditions, Acropora reward dedicated reefers with dynamic growth and striking displays of color. Location Acropora corals are native to the vibrant reefs of the Indo-Pacific, including regions like Fiji, Tonga, the Solomon Islands, and the Great Barrier Reef. They are typically found in high-energy zones near reef crests and upper slopes, where strong currents deliver nutrients and maintain water clarity. In their natural habitat, Acropora provide shelter and structure for various small reef inhabitants, such as gobies, crabs, and shrimp, contributing to the reef's biodiversity. Water Chemistry Acropora corals thrive in aquariums with stable and pristine water conditions. They rely on consistent levels of essential elements to grow and maintain their skeletal structure: Calcium: 420-440 ppm Alkalinity: 8-9.5 dKH Magnesium: 1300-1450 ppm Nitrates:
