Care
Chaetodon nippon requires a well-established aquarium with plenty of swimming space and a variety of live rock formations for shelter. They are not considered reef-safe as they may nip at corals and sessile invertebrates. A varied diet of meaty foods, including mysis shrimp and marine flakes, is essential for maintaining their health and coloration.
Reproduction
In the wild, Japanese Butterflyfish form monogamous pairs during the breeding season. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. In the home aquarium, breeding is rare and challenging.
Habitat
Native to the Northwest Pacific, particularly around Japan, this species is found in coastal reefs and rocky outcroppings. They prefer clear waters where they can forage for their preferred diet of polyps, benthic invertebrates, and algae.
