The Colt coral is a soft, branching coral that is found in Indo-Pacific coral reefs. It does not have the calcium carbonate skeleton of the reef building corals. It is a hardy aquarium species and is commonly cultured. Like other corals, its tissues are home to photosynthetic algae known as zooxanthellae which provide the coral with oxygen and nutrients.
