Holacanthus tricolor
Rock Beauty (Holacanthus tricolor) is a reef-dwelling angelfish of the western Atlantic and Caribbean, famous for its bright yellow body, black rear half, and blue-edged fins.

Identification points
- Bright yellow head and front half with a velvety black rear half and tail
- Electric-blue margins on the dorsal, anal, and caudal fins
- Tall, laterally compressed angelfish body with a small mouth and pointed snout
Habitat
Shallow coral reefs, rocky reef ledges, spur-and-groove zones, and reef slopes, usually near abundant sponge growth; juveniles often shelter in crevices and among finger coral or rubble.
Bait notes
Not a targeted gamefish and is rarely angled on purpose. If incidentally caught on small reef gear, it may take tiny pieces of shrimp, clam, or squid, but most anglers leave it alone for aquarium/recreational observation.
Behavior
A territorial reef angelfish that grazes on sponges and filamentous algae and picks small invertebrates from the reef. Often seen alone or in pairs, closely associated with structure and quick to retreat into cover when disturbed.
Caution
Reef species protection may apply in some locations, and collection for the aquarium trade can be regulated. Handle gently to avoid stressing the fish and damaging reef habitat; if kept for food in unusual circumstances, verify local advisories and rules first.
Fishing notes
Avoid targeting this reef species; it is better admired in the water than caught. Any capture should be minimized and handled carefully, then released promptly with wet hands or a net if local regulations allow.
