With its beautiful and unique morphology, the Heniochus Butterfly makes one of the most eye-catching fish in a tank. The most distinct feature is the presence of long white pennant along its elongated first dorsal spine, and for this feature, it is also named the pennant bannerfish. The Heniochus Butterfly can grow up to 8 inches, and therefore a more spacious tank is always better for this fish. It is only suited to a fish only system, and thrives well in a temperature range of 74-80 degrees Fahrenheit, and pH above 8.0. Make sure to provide an adequate biological filtration to keep ammonia and nitrate at undetectable levels. Though this fish is not considered aggressive, but it may become territorial with other members of the species. It is better to keep the Heniochus Butterfly singly or as a school of 3 or more in a larger tank, and should not be combined with chronic-fin nippers, such as many triggerfish, damselfish and some angelfishes, which can nip at the trailing fins of this Butterfly fish. It is not at all considered reef safe and should not be housed with any sessile invertebrates. However, the Heniochus Butterfly is found safe with crabs, snails and shrimps. It needs feeding at a regular interval with Mysis shrimp, and other meats and plankton foods, also with soaked frozen foods in vitamins in order to prevent it from head and lateral line erosion(HLLE) ailment.
