Care
Pearl-scaled Butterflyfish are considered moderate to care for. They require a well-established aquarium with plenty of live rock for grazing and hiding. They are not considered reef safe as they may nip at corals and invertebrates. A varied diet of meaty foods, algae, and high-quality marine flake or pellet food is essential for their health.
Reproduction
Like many butterflyfish, Chaetodon xanthurus is oviparous, with pairs forming during the breeding season and engaging in a courtship dance before releasing eggs and sperm into the water column. The eggs are pelagic, drifting with the currents until hatching.
Habitat
Pearl-scaled Butterflyfish are found in the Western Pacific, from Indonesia to the Philippines and north to Japan. They inhabit coral-rich areas of lagoon and seaward reefs, typically at depths of 3 to 20 meters. They are often seen in pairs or small groups, swimming close to the reef structure.
