Common name: Yellowsnout butterflyfish

General information

The Blackwedged Butterflyfish, Chaetodon flavirostris, is a striking species known for its vibrant coloration and distinctive black wedge on the tail. This species is not as commonly kept as some other butterflyfish due to its specific dietary requirements and sensitivity to aquarium conditions.

Care

Chaetodon flavirostris requires a well-established aquarium with plenty of live rock for grazing and hiding. They are known to be picky eaters, often preferring live foods or frozen preparations that include sponges and tunicates. A varied diet is crucial for their health. They are best suited for experienced aquarists who can meet their care requirements.

Reproduction

In the wild, Blackwedged Butterflyfish form monogamous pairs during the breeding season. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. Raising the larvae in captivity is challenging and not commonly done in home aquariums.

Habitat

This species is found in the Indo-Pacific region, from East Africa to the Hawaiian, Marquesan, and Ducie islands, north to southern Japan, south to Lord Howe and Rapa islands. They inhabit coral reefs and are often seen in pairs or small groups, usually at depths of 3 to 35 meters.
