Saltwater angelfish have come spanning the tropics Indian Atlantic and western Pacific oceans. Most angelfishes limit themselves into the shallows of the reef venturing deeper than 50 meters. The recently described Centropyge abei is known into depths of 150 m. Freshwater angelfish are found in a large area in South America.
Their range comprises the states of Colombia, Guyana, Suriname, French Guiana, Peru and Brazil. They live from different river systems drainage, including the Negro, Amazon and Orinoco rivers.
