Spotfin Butterflyfish

Chaetodon ocellatus

Spotfin Butterflyfish (Chaetodon ocellatus) is a reef-associated butterflyfish found in the western Atlantic, especially the Caribbean and Florida. It feeds mainly on small benthic invertebrates and coral-associated organisms, and is more often observed by divers than targeted by anglers.

Identification points

Rounded butterflyfish profile with a narrow snout and small terminal mouth

Habitat

Shallow coral reefs, reef edges, patch reefs, and rocky areas with abundant growth in the western Atlantic; usually in clear, warm saltwater near structure.

Bait notes

Not a standard game fish. If taken incidentally, tiny natural baits such as small shrimp bits, squid strips, or reef worms are more relevant than lures; hook size must be very small.

Behavior

Typically occurs in pairs or small groups and picks at small invertebrates from reef surfaces and crevices. It is diurnal, wary, and closely tied to reef structure rather than open water.

Caution

Reef fish consumption caution applies in some areas due to possible ciguatera risk; check local advisories. Handle carefully with wet hands or a soft net, and avoid prolonged air exposure.

Fishing notes

Best approached as a reef observing species rather than a target. It may peck at stationary baits presented very delicately near structure, but catch-and-release handling should be minimal because it is fragile.
