what is coral

Coral is a type of marine organism that forms the foundation of reef ecosystems. It exists as tiny polyps that secrete calcium carbonate to build hard skeletons. These structures provide habitat for countless marine species, supporting biodiversity in oceans worldwide. Understanding coral helps us appreciate their role in protecting coastlines and sustaining fisheries.

When choosing a reef aquarium, select corals that match your lighting and water conditions. Species like brain coral or staghorn coral thrive in stable environments. Regular maintenance, such as cleaning and checking water quality, is essential for healthy coral growth. Always research specific needs before purchasing to ensure long-term success.
