However, the Golden Damselfish also has vibrant yellow on its underbelly and fins, giving it a striking contrast with the black body. They can be found in shallow reefs or lagoons in the Central Pacific Ocean where they hide among the rockwork. They should be kept in an aquarium with at least 30 gallons, as well as significant live rock. They enjoy a diet of algae, crustaceans and other small invertebrates.
