Cheek without scales; 5-9 scales in supra temporal patch; inner surface of pectoral fin densely covered with scales; posterior angle of opercular fully scaled. Body color is yellowish or bronze, lighter below. Centers of many scales with a white or light blue spot. Sometimes irregular dark indistinct bars on sides and a square black blotch above pectoral fin bordering below the lateral line. Three blue streaks or series of blue spots radiate forward and ventrally from the eye. The fins are whitish or yellowish; the pelvic dusky, the edge of the dorsal fin is reddish.

Biologie
    Fachlexikon (Englisch) (z.B. epibenthic)
Inhabit coral reefs, coralline lagoons, seagrass beds, mangrove swamps and coastal sand and rock areas. Adults solitary or in small schools; juveniles form large schools in shallow, sheltered sandy areas, also harbors where in seagrasses, algae or sponge habitats at various depths. Feed on echinoderms, mollusks and crustaceans, and to some extent on polychaetes and fish. A protogynous hermaphrodite (Ref. 55367). May have a coppery or iodine taste or smell in the Indian Ocean (Ref. 2295, 11888). It has been shown that this species can survive for long periods in salinities as low as 10 parts per thousand and therefore it is a potential estuarine aquaculture species (Ref. 2295). Utilized as a food fish.
