Four-eyed Butterflyfish
Chaetodon capistratus
The Four-eyed Butterflyfish is a small tropical reef fish with a false eye spot near the tail and a dark eye stripe that helps confuse predators. It is common on shallow Caribbean and western Atlantic reefs and feeds mainly on small benthic invertebrates and coral-associated prey.

Identification points
- Dark vertical eye band across the true eye
- Large black eyespot near the rear dorsal flank/peduncle
- Yellowish to pale body with a rounded butterflyfish profile
Habitat
Shallow coral reefs, reef flats, patch reefs, and seagrass edges in warm, clear tropical western Atlantic waters, usually in pairs or small groups near structure.
Bait notes
Not a standard target for anglers and rarely taken intentionally. If attempted, tiny natural baits like shrimp bits or small worm fragments on very light tackle are most relevant; small soft plastics or flies that imitate tiny reef prey may draw strikes.
Behavior
Diurnal and wary, it picks at tiny crustaceans, worms, and coral mucus/organisms from reef surfaces. The rear eye spot and body eye band are thought to aid predator avoidance, and it retreats quickly into cover when disturbed.
Caution
Reef-associated tropical fish can be subject to local collection or capture restrictions; check regulations before attempting to take one. Handle gently because the species is small and easily stressed; not generally considered a food fish.
Fishing notes
Best approached only by reef observers or very light-tackle anglers in areas where capture is legal. Use tiny hooks, minimal weight, and delicate presentations tight to structure; avoid prolonged handling and release immediately.
