Black and white heniochus have tall, striped bodies, with yellow caudal fins and a trailing white dorsal fin. Their small mouths are ideal for eating tiny prey and plants on the ocean floor.
Heniochus are versatile fish; they can live solitarily, in pairs, or in larger groups. They are rather peaceful and can be quite helpful to other fish. Juvenile and adult heniochus will eat parasitic flatworms from the scales of other fish.
Black and white heniochus are intensively harvested for the aquarium industry within the Philippines; nevertheless, there appear to be no overall threats to this widespread species.
