Posterior portion of parieto-supraoccipital and predorsal region conspicuously lighter than surrounding areas. Trunk with three conspicuous light cream bars, extending transversely from dorsal midline to ventral surface. First bar situated on posterior third of dorsal fin; its anterior margin continuing as thinner bar below lateral line and reaching ventral midline.

Third bar shortest, immediately anterior to caudal fin and variably reaching ventral surface. Superposed on above pattern, dorsal and most of ventral surface covered with small dots smaller then pupil diameter, formed by concentration of black chromatophores and giving sprinkled pattern. Fins with transverse, inconspicuous brown bands formed by concentration of chromatophores on rays; bands more visible on leading rays.
