Care
Pelewensis Butterflyfish 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, including marine fish, crustacean flesh, and mysis shrimp, is essential for their health.
Reproduction
Breeding Pelewensis Butterflyfish in captivity is challenging and rarely successful. In the wild, they are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs.
Habitat
Native to the Western Pacific, particularly around Palau and Yap, Pelewensis Butterflyfish are found in coral-rich areas of lagoons and seaward reefs. They prefer clear waters and are typically seen at depths where light penetration supports coral growth.
