Heniochus fish over a coral bank

The Black and White Heniochus Butterfly Fish is also known as the poor man's Moorish Idol. While the Black and White Heniochus Butterfly Fish looks similar to the Moorish Idol the Black and White Heniochus is significantly different. It is much easier to care for captivity and is one of the hardier butterfly fishes available. They are very attractive with black and white broad stripes and long streaming dorsal fins much like those of the Moorish idol.
