Identification points

Yellow to green body with darker vertical bars or barred pattern
Parrot-like beak formed by fused teeth
Robust oval reef fish with a blunt head and continuous dorsal fin

Habitat

Coral reefs, reef flats, lagoons, and seaward reef slopes in clear tropical saltwater, usually close to hard-bottom areas with abundant algal growth.

Bait notes

Not a prime target for anglers and is rarely sought as a gamefish. If incidentally targeted, small pieces of seaweed/sponge-like vegetable baits or tiny reef lures may draw interest, but catch rates are typically low.

Behavior

Diurnal grazer that forages by biting and scraping algae from coral and rubble; often seen singly or in small groups and may shelter in reef structure at night.

Caution

Reef-fish consumption can carry ciguatera risk in some locations; use caution with any large reef predator prey chain nearby and follow local advisories. Many areas restrict harvest of parrotfishes, so check local regulations.

Fishing notes

Best approached with very light tackle near shallow reef edges if legal to harvest; most captures are incidental while reef fishing. Avoid damaging coral, and check local rules before attempting to keep or target parrotfish.
