Saddle Butterflyfish

Chaetodon ephippium

The Saddle Butterflyfish is a reef-associated butterflyfish with a bold black “saddle” blotch on the rear upper body and a yellow-white body. It is a coral-reef feeder that mainly picks at small invertebrates and coral polyps.

Identification points

  • Large black saddle-shaped patch on the rear upper back behind the dorsal fin
  • White to pale yellow body with a dark eye band and yellowish rear section
  • Rounded butterflyfish profile with a pointed snout and continuous dorsal fin

Habitat

Warm Indo-Pacific coral reefs, lagoon patch reefs, and outer reef slopes, usually around branching and massive corals in shallow to moderate depths.

Bait notes

Not a targeted sportfish and is seldom caught intentionally. In aquarium/collection contexts it responds to tiny live foods such as brine shrimp, copepods, and finely chopped marine fare; standard fishing baits are generally ineffective.

Behavior

Diurnal and often paired; it forages by pecking at coral polyps and small benthic invertebrates, and may be territorial around feeding areas.

Caution

Reef-associated and not a typical food fish; avoid taking it for consumption. Handle carefully to prevent damage to its delicate mouth and fins, and note that coral-reef collection may be regulated in some areas.

Fishing notes

If encountered while reef fishing, use very small hooks and delicate presentations near coral structure, but avoid targeting it because of its small size and reef sensitivity. Best treated as an observation species rather than a catch.
