🐠 Longfin Bannerfish (Heniochus acuminatus)

A White Body With Two Bold Black Bands and a Long Pennant-Like Dorsal Fin • Nicknamed the "Poor Man's Moorish Idol" • A Hardier, More Approachable Alternative

 

📋 The Longfin Bannerfish, also known as the Pennant Coralfish, Reef Bannerfish, or Coachman, has an elegant white body marked with two bold black vertical bands, yellow accents on the pectoral, caudal, and dorsal fins, and a long, trailing, pennant-like dorsal fin filament that gives the species its name.

It comes from a vast range across the Indo-Pacific, from East Africa and the Persian Gulf to the Society Islands, inhabiting deep, protected lagoons and reef slopes, often below 15 metres. Every Longfin Bannerfish we ship is feeding well.

Nicknamed the "Poor Man's Moorish Idol" for its close resemblance to the far more delicate and challenging true Moorish Idol, this species is considerably better suited to aquarium life while offering a similar striking look. A charming natural behaviour: juveniles are documented cleaning parasites off other fish. This species is hardy and adapts well once settled, and can be kept in small groups or pairs if all individuals are introduced simultaneously. This species is not reef safe, and will eat invertebrates and nip at corals if not well fed, so a varied, generous diet matters. It reaches up to 25cm, so a 470L tank suits it well.
