Care
Heniochus diphreutes is a hardy species that adapts well to captivity. It requires a large tank with plenty of swimming space and stable water conditions. This species is not considered reef-safe as it may nip at soft corals and some invertebrates. A varied diet of meaty foods, marine flakes, and pellets is essential for their health.
Reproduction
In the wild, Schooling Bannerfish form large groups and are pelagic spawners, releasing their eggs into the water column. Breeding in captivity is rare and challenging, but maintaining a group in a species-only tank with controlled conditions may encourage spawning behavior.
Habitat
Heniochus diphreutes is commonly found in open waters and reef slopes, often in large schools. They are distributed across the Indo-Pacific region, from the Red Sea and East Africa to the Hawaiian Islands and Japan.
