Latin Name - Heniochus acuminatus
Common Name - Black and White Heniochus
Also known as - Longfin Bannerfish, Heniochus Butterfly
This is one of the more durable of the butterflyfish species, and one of a few butterflies that are generally reef safe. It is a very active fish and should be housed in a tank of at least 55 gallons. It will tolerate members of its own kind in the same aquarium, as long as they are introduced to the tank at the same time. Members of a captive group will form a dominance hierarchy. Individuals fight for dominance by butting foreheads and trying to push each other backwards and when they display at each other. It will sometimes clean other fishes. This is a zooplankton feeder that can be housed with corals and other ornamental invertebrates. An occasional individual may nip at Xenia or other soft corals. Most specimens are around 2.5-3.5" Shown are huge specimens which have dorsal "streamers" longer than those of smaller specimens.
