Common name: Threebanded butterflyfish

General information

The Threebanded Butterflyfish, Chaetodon humeralis, is a striking species known for its distinctive coloration and patterns. This fish is characterized by its white body with three black vertical bands and a touch of yellow on the fins. It is a member of the family Chaetodontidae, which is renowned for its diverse and colorful species.

Care

Chaetodon humeralis requires a well-established aquarium with plenty of live rock for grazing and hiding. They are not considered reef-safe as they tend to nip at corals and sessile invertebrates. A varied diet of meaty foods, algae, and high-quality marine flakes or pellets is essential for their health.

Reproduction

In the wild, Threebanded Butterflyfish form monogamous pairs during the breeding season. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic, drifting in the currents until they develop into juveniles and settle into the reef.

Habitat

This species is found in the Eastern Pacific, from the Gulf of California to Peru, including the Galapagos Islands. They inhabit rocky reefs and coastal lagoons, typically at depths ranging from 3 to 30 meters. Chaetodon humeralis is often observed in pairs or small groups, navigating through the complex reef structures.
