Common name: Blackback butterflyfish

General information

The Blackback Butterflyfish, scientifically known as Chaetodon melannotus, is a striking species admired for its bold coloration and graceful swimming. It is characterized by its deep yellow body, contrasting black dorsal area, and a prominent black vertical band through the eye, which helps in camouflaging the eye and confusing predators.

This species is not as common in the aquarium trade as some other butterflyfish due to its specific dietary requirements and sensitivity to captive conditions. However, for advanced hobbyists, it can be a rewarding challenge to maintain.

Care

Chaetodon melannotus requires a well-established aquarium with plenty of live rock for grazing and hiding. They are known to be picky eaters, often feeding on coral polyps and benthic invertebrates in the wild. In captivity, their diet should include a variety of foods such as mysis shrimp, brine shrimp, and high-quality marine flakes and pellets to ensure a balanced diet.

Stable water conditions and a peaceful tank environment are crucial for the well-being of this species. They are best kept with non-aggressive tank mates, as they can be shy and easily outcompeted for food.

Reproduction

In the wild, Blackback Butterflyfish are pelagic spawners, releasing their eggs into the water column where they are fertilized and dispersed by currents. Breeding them in captivity is challenging and rarely achieved, but understanding their natural spawning behavior can provide insights for potential breeding programs.

Habitat

The Blackback Butterflyfish is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit coral-rich areas of lagoons and seaward reefs, typically at depths ranging from 1 to 30 meters.

Their preference for coral environments makes them sensitive to changes in coral health, and they can serve as indicators of reef well-being in their natural habitat.
