Also known as the Black Pyramid Butterflyfish or Brown-and-White Butterflyfish, it naturally forms large schools above reef edges where it feeds primarily on drifting zooplankton. More adaptable to aquarium feeding than many coral-dependent butterflyfish, this active and sociable species can make an impressive addition to a spacious, mature marine aquarium, although its size, frequent feeding requirements and occasional interest in soft corals must be considered.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eCommon Name:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eZoster Butterflyfish, Zoster Butterfly, Black Pyramid Butterflyfish, Brown-and-White Butterflyfish\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eScientific Name (Latin):\u003c\/strong\u003e\u003cbr\u003e\u003cem\u003e\u003cspan\u003eHemitaurichthys zoster\u003c\/span\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eMaximum Size:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eUp to approximately 18 cm in total length.
