Description

Chaetodon semilarvatus has a bright yellow body with a broad vertical black band on the head covering the eye. Another black band is on the caudal peduncle. The fins are yellow with black edges. It is active and swims in pairs or small groups. In an aquarium, it is relatively hardy but requires a varied diet. It can be kept with other peaceful fish. It tends to nip at corals, so not recommended for reefs. Its intense coloration makes it a very decorative fish.
