Indian Redfin Butterflyfish
Chaetodon trifasciatus
A reef-associated butterflyfish of the Indo-Pacific, the Indian Redfin Butterflyfish is strongly tied to live coral and is often seen in pairs or small groups. It is not a common angling target and is best appreciated by divers and snorkelers rather than anglers.

Identification points
- Yellow body with three bold black vertical bars, including one through the eye and one near the tail
- Bright red-orange patch on the rear back/dorsal area, especially vivid in adults
- Long, pointed butterflyfish snout and a pale tail with dark edging
Habitat
Shallow coral reefs, lagoon reefs, and outer reef slopes with abundant live branching corals; usually in clear tropical saltwater from nearshore reef flats to deeper reef edges.
Bait notes
Not a practical bait species and rarely targeted by anglers. It does not respond to typical gamefish baits; aquarium collection is specialized and should follow local regulations and coral-reef protection rules.
Behavior
Day-active coral feeder that picks at coral polyps and small benthic invertebrates; typically wary, territorial around feeding areas, and often observed swimming in pairs or small family groups.
Caution
Handle carefully because reef fins and spines can puncture skin; avoid contact with coral. In many places reef butterflyfishes are protected or subject to local collection restrictions, so check regulations before taking any.
Fishing notes
No standard sport-fishing techniques apply; avoid targeting coral reef butterflyfishes on reefs. If observed while fishing, release immediately with minimal handling and do not drag tackle across coral.
