Care
Spot-tail Butterflyfish are moderately challenging to keep in home aquariums. They require a well-established tank with plenty of live rock for grazing and hiding. This species is not considered reef-safe as it may 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, Spot-tail 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 quite challenging due to their planktonic nature and specific dietary requirements.
Habitat
Chaetodon ocellicaudus is found in the Indo-Pacific region, from the Maldives to Japan, and south to Australia. They inhabit coral reefs and lagoons, typically at depths of 1 to 30 meters. They are often observed in pairs or small groups, swimming close to the reef structure.
