Care
Silver Butterflyfish are moderately difficult to care for due to their specific dietary requirements. They thrive in well-established aquariums with plenty of live rock for grazing and hiding. These fish are not coral-friendly and may nip at soft and stony corals, so they are best kept in a fish-only or fish-only with live rock (FOWLR) setup. A varied diet of meaty foods, including marine fish, crustacean flesh, and mysis shrimp, is essential for their health.
Reproduction
In the wild, Silver Butterflyfish form monogamous pairs during the breeding season. They are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. Raising the larvae in captivity is challenging due to their planktonic stage and specific feeding requirements.
Habitat
Silver Butterflyfish are found in the Western Pacific, from southern Japan to Taiwan and the South China Sea. They inhabit coral reefs and rocky outcrops, typically at depths ranging from 3 to 30 meters. They prefer clear waters with strong currents where they can feed on zooplankton.
