Corals are animals, as they do not produce their own food. Coral benefit from a symbiosis of animal and plant life. Coral (or coral polyps) are small organisms with soft bodies. They are made up of a protective skeleton made of limestone. This is called a “calicle” and it’s the harder base of the coral. Polyp calicles join each other and create a colony that acts and moves as a single organism.
Corals can be added to your reef teeming with fish, or you can keep coral on it’s own without introducing fish to the tank. Come by and check out our in store reef, and look at our coral and frag tables or yourself!
