The Longfin Bannerfish, also known by its scientific name Heniochus acuminatus, is a species of marine fish that belongs to the family Chaetodontidae. It is primarily found in the Indo-Pacific region, including the Red Sea, the Maldives, and the Great Barrier Reef.

Here are some key features and characteristics of the Longfin Bannerfish:

Appearance: The Longfin Bannerfish has a striking appearance with a compressed, disc-shaped body. It has a predominantly black coloration with a prominent white banner-like dorsal fin, which extends from the forehead to the tail. The anal fin and caudal fin are also white, while the pectoral fins are elongated and yellow.

Size: These fish can grow up to about 20 centimeters (8 inches) in length.

Behavior: Longfin Bannerfish are generally peaceful and social fish. They are known to form small groups and are often seen swimming in pairs or in small schools. They are diurnal, which means they are most active during the day.

Habitat: They inhabit coral reefs and lagoons, preferring areas with rich coral growth and ample hiding spots. They can be found at varying depths, typically ranging from 1 to 30 meters (3 to 100 feet).

Diet: Longfin Bannerfish are omnivorous, feeding on a combination of small invertebrates, zooplankton, and algae. In captivity, they can be fed a diet consisting of high-quality marine-based flake or pellet foods, supplemented with small pieces of fresh or frozen seafood and algae.

Aquarium Care: If you are considering keeping Longfin Bannerfish in an aquarium, it's important to provide them with a suitable environment. A tank with a capacity of at least 100 gallons is recommended to accommodate their active swimming habits. They require well-maintained water conditions with stable temperature, pH, and salinity levels. It's also advisable to include plenty of live rock in the aquarium, which will provide hiding places and grazing surfaces for them.

Caution: While Longfin Bannerfish are generally peaceful, they may become territorial towards other fish of the same species or similar-looking species. Care should be taken when introducing them to an aquarium with other bannerfish or closely related fish.
