Acropora

Acropora sp.

Family: Acroporidae

📍 Indo-Pacific Reef Systems

Ask Finn

Acropora is the largest and most diverse genus of stony corals on earth, encompassing hundreds of species forming branching, table, and bushy morphologies in nearly every colour imaginable. They are the primary reef-building corals and are the benchmark for advanced reef aquariums — demanding pristine, stable water chemistry, very high light, moderate to high flow, and expert-level nutrient management. In well-maintained SPS tanks they reward with breathtaking growth and colouration.
