Blackback Butterflyfish
Chaetodon melannotus
Blackback Butterflyfish is a reef-associated Indo-Pacific butterflyfish that feeds mainly on coral polyps and small benthic invertebrates. It is generally encountered in clear coastal and outer-reef habitats and is more of an ornamental reef species than a target for anglers.

Identification points
- Bright yellow body with a distinct dark, blackish patch over the rear dorsal area/back.
- Compressed butterflyfish shape with a pointed snout used for picking at coral.
- Patterned facial markings and a pale-to-yellow body that contrasts with the dark rear saddle.
Habitat
Coral-rich reef slopes, lagoon edges, seaward reef fronts, and sheltered outer-reef habitats in warm tropical Indo-Pacific waters, usually where live coral cover is good.
Bait notes
Not a standard sport or food-fish target. In aquarium or observational contexts it feeds on coral polyps, small crustaceans, and prepared marine foods; it is not normally taken on hook-and-line bait or lures.
Behavior
Typically occurs singly or in pairs and picks at coral heads and rocky reef structure for small prey. It is diurnal, wary, and closely tied to coral habitat rather than open water.
Caution
Reef-dependent species; many localities restrict collection or harvest of butterflyfishes. Do not consume unless local regulations clearly allow it, and avoid collecting from coral reefs where damage or protected status may apply.
Fishing notes
No practical recreational fishing value in most areas because it is small, reef-bound, and often protected by local reef regulations. Avoid reef capture methods that damage coral habitat.
