Based on both sexes, except when noted. Dorsal portion of head and trunk pale brown, lighter ventrally. Three narrow, irregular, oblique dark brown stripes on postorbital portion of head and humeral region. Anterior stripe very short, from posterodorsal margin of eye, running posterodorsally to include only two scales; indistinct in some specimens. Median stripe from posteroventral margin of eye, running posterodorsally to two scale rows short from dorsal midline; usually interrupted, especially in larger specimens, or irregular, or fused to other dark marks. Posterior stripe extending from anterior margin of opercle to humeral region. Mid-dorsal stripe on supra-occipital, extending three scales posteriorly, more conspicuous in smaller specimens. Scales on cheek and opercular series with melanophores scattered on distal margins, darker in cheek scales, more diffuse in scales over opercular series, producing spotted pattern. Patches of melanophores forming series of densely pigmented spots around ventral margin of eye. Skin flaps surrounding neuromasts, especially those in the dorsal portion of the snout, densely pigmented with melanophores in adults, but not in smaller specimens. Remainder of trunk with melanophores not forming discernable patterns. Smaller specimens with brownish stripes all over flank, formed by thin lines of pigment on distal margin of scales. Stripes usually forming chevron-like marks with angle on midline of flank, pointing anteriorly, separated from each other by two or three scales. Occasionally, chevron-like marks separated by one scale, seemingly forming double stripes or reticulate patterns. Some marks with Y-shaped ends dorsally or ventrally (see ‘Color in life’,

Lower lip pale orange to reddish. Posterior region of opercle bright yellow. Top of head and predorsal area with golden hue. Flanks yellowish plumbeous. Abdominal region white to beige. Chevron marks red to orangish red, occasionally broken into spots both dorsally and ventrally. Pectoral fin hyaline to light yellow. Dorsal and anal fins of males light yellow, occasionally light bluish posteriorly, near base. Dorsal- and anal-fin live coloration of females not recorded. Caudal-fin in males light yellow, with dark brown stripes. In females, light orangish yellow with black stripes.
