Painted Sweetlips

Diagramma pictum

Painted Sweetlips (Diagramma pictum) is a reef-associated grunter with a deep body and striking spotted juvenile pattern that fades with age. It occurs on coastal reefs, lagoons, and sandy areas near structure across the Indo-West Pacific; adults are wary and often feed at dusk and night.

Identification points

Deep, laterally compressed body with a steep forehead and thick lips
Juveniles strongly spotted and banded; adults become more uniformly gray-brown with faint spotting
Long continuous dorsal fin with prominent spines and a slightly rounded caudal fin

Habitat

Shallow coral and rocky reefs, lagoon drop-offs, and adjacent sandy or rubble bottoms; juveniles often shelter in sheltered reef flats, mangroves, and seagrass near structure.

Bait notes

Use fresh strips of squid, shrimp, crabs, or small baitfish; soft plastics, jerk shads, and bottom-presented natural baits can work around reef edges. Smaller hooks and natural presentations outperform bulky rigs.

Behavior

Nocturnal to crepuscular feeder that forages over reefs for crustaceans, mollusks, worms, and small fish; juveniles commonly occur in small groups, while larger adults are usually solitary and cautious.

Caution

Sharp dorsal spines can puncture hands; handle carefully. Like many reef fish, larger individuals may carry ciguatera risk in some tropical areas, so local consumption advisories matter.

Fishing notes

Fish close to reef edges, bommies, and current lines on light to medium tackle; let baits soak near bottom and be ready for strong first runs. Target dusk, night, or low-light periods, and avoid heavy snag-prone tackle if possible.
