Care

Caring for Masked Butterflyfish can be challenging due to their specialized dietary requirements. They primarily feed on coral polyps and benthic invertebrates in the wild, so providing a varied diet that includes marine meats, mysis shrimp, and high-quality frozen preparations is essential for their health in captivity. A larger aquarium with plenty of swimming space and live rock for grazing is recommended.

Reproduction

In the wild, Masked 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 complex and not commonly achieved by hobbyists.

Habitat

Chaetodon semilarvatus is native to the Red Sea and Gulf of Aden. They are typically found in coral-rich areas of lagoons and seaward reefs, often at depths ranging from 3 to 20 meters. Their preference for coral habitats makes them sensitive to changes in water quality and coral health.
