Black & White Heniochus Butterflyfish
The Black & White Heniochus Butterflyfish (Heniochus acuminata), also known as the Longfin Bannerfish, features a white body with two bold, vertical black bands and a distinctive, exceptionally long dorsal fin that flows gracefully as it swims. Unlike many other butterflyfish, this species is known for its relatively peaceful temperament, making it an excellent candidate for a community tank. This is known as a bannerfish and there are a few very similar varieties. The very first bannerfish was discovered by Swedish naturalist Carl Linnaeus, but the prize for the “acuminata” species goes, once again, to the great zoologist Georges Cuvier in 1816.

Colin Clark –
Added this butterflyfish to my 55-gallon tank and it has been thriving. The long dorsal fin is striking and it doesn’t stress other fish. Very peaceful and active in the middle of the tank.
Harry Abraham –
Looks beautiful in the tank. The black and white pattern is clear and the fish swims gracefully. It’s not aggressive and gets along well with my clownfish and gobies.
Stewart Arnold –
Perfect addition to my reef tank. It’s calm, colorful, and doesn’t chase smaller fish. The fin movement is elegant and adds a lot of visual interest.
