Care

Chaetodon selene requires a well-established aquarium with plenty of live rock for grazing and hiding. They are generally peaceful but can be territorial with other butterflyfish. A varied diet of marine meats, algae, and high-quality prepared foods is essential for their health. They are best kept in a large tank with stable water conditions to thrive.

Reproduction

In the wild, Yellow-dotted Butterflyfish are oviparous, with pairs forming during breeding. They engage in a courtship dance before spawning, releasing eggs into the water column that are then fertilized. In the aquarium, breeding is rare, but providing a stress-free environment may encourage spawning behavior.

Habitat

This species is found in the Indo-Pacific region, from the Maldives to Japan, and south to Indonesia. They prefer coral-rich areas and clear lagoons, typically at depths of 3 to 20 meters. Their natural habitat includes a variety of live corals, which they use for food and shelter.
