Common name: Blackback Butterflyfish

General information

The Blackback Butterflyfish, scientifically known as Amblyglyphidodon melanopterus, is a vibrant and attractive species that adds a splash of color and activity to any marine aquarium. This species is known for its striking black dorsal fin which contrasts beautifully against its yellow body. They are generally peaceful but can be territorial towards their own kind or similar-looking fish.

Care

Amblyglyphidodon melanopterus requires a well-established aquarium with plenty of swimming space and hiding places among live rock. They thrive in a stable environment with consistent water quality. A varied diet of meaty foods, including marine fish, crustacean flesh, and mysis shrimp, supplemented with algae, will help maintain their health and coloration.

Reproduction

In the wild, Blackback Butterflyfish form monogamous pairs during the breeding season. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. The eggs are pelagic, drifting in the open ocean until hatching. In the home aquarium, breeding is rare, but maintaining a pair in a large, species-specific setup may encourage spawning behavior.

Habitat

Native to the Indo-Pacific region, Amblyglyphidodon melanopterus is commonly found in shallow reefs and lagoons, often in areas with strong water movement. They are typically seen at depths ranging from 2 to 20 meters, where they swim in pairs or small groups.
