Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 9 - 11; Anale stekels: 1; Anale zachte stralen: 7 - 11; Wervels: 26. Brick-red in color, usually with two paler bars (one across pectoral base, the other centered on the space between the two dorsal fins); snout and chin fiery red, broken by two pale horizontal stripes from the dorsal and ventral margins of the pupil, respectively. The dorsal stripe passes anteriorly across the nostrils, the ventral stripe crosses the upper jaw and may continue onto the chin (Ref. 46430).
Body shape (shape guide): fusiform / normal.
Collected from lagoons as well as from oceanic drop-offs (Ref. 46430). Forms schools and feeds on plankton (Ref. 46430).
