DescriptionAcropora (Acros) are found all throughout tropical reefs around the world. While beautiful, they are a difficult species to care for and not for beginning hobbyists. Acros require perfect and stable water conditions, strong lighting and strong alternating flow to do their best. Acropora are found in some of the strongest current areas of the reef and benefit greatly from strong water movement in the home aquarium. Water movement is essential for bringing nutrients to coral and more importantly removing waste away from them. Acropora even grow in patterns to adapt to the flow in a given area.
