General Husbandry: Occasionally seen in the trade having a laterally compressed body and a small mouth, such as angelfishes and butterflyfishes, and having a pale grey body with a wide vertical white bar edged on both sides in dark brown just behind the eyes.
Can be maintained in reef or fish-only aquariums having wide-open swimming areas and somewhat turbulent, well-oxygenated water flow.
