Care

Golden Butterflyfish require a well-established aquarium with plenty of swimming space and a mature reef environment. They are not the easiest species to keep, as they have specific dietary needs that include a variety of meaty foods and marine algae. They may also nibble on soft and stony corals, so they are not the best choice for a reef tank with a wide variety of corals.

Reproduction

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

Habitat

Chaetodon aureofasciatus is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They prefer clear lagoon and seaward reefs, typically at depths ranging from 1 to 30 meters. This species is often observed in pairs or small groups, swimming in close proximity to the reef structure.
