overviewGreat news Chaetodon fans, the Dusky Butterfly Fish is finally here! Chaetodon flavirostris, also commonly known as the Black Butterflyfish, or Orange-Nosed Butterfly, is a challenging but highly rewarding addition reserved for the most confident aquarist experienced in keeping large, corallivorous butterflies.
The Dusky Butterflyfish's contrasting aurora of golden orange and yellow rings encircle a moody purple-black, disc-shaped body. As they mature, the snout-like mouth turns white with a yellow band, the body darkens, and a characteristic lump emerges on the forehead.
Notoriously difficult to feed in captivity, these omnivores primarily feed on coral polyps, benthic invertebrates and algae in the wild. A diet of vitamin-enriched fresh clams may be needed in the beginning. Once eating, offer vitamin-enriched mysis and brine shrimp.
For best success, a 125-gallon or larger, fish-only aquarium is recommended with live rock (and fast-growing corals you expect to be consumed).
