Color: Preserved colour pale grey to pale tan with 3 triangular dark brown saddle-like bars dorsally on body. A dark brown band run across posterior interorbital and anterior occiput; a dark brown spot below base of pectoral fin; head and body with many small pale spots (most about half pupil diameter), faint or absent on paler parts of body but very evident on edges, within dark bars, and on head where ground colour darker; around eye are narrow pale bands and spots; pale lips encircled with a narrow dusky band; a thin dark brown line midventrally on abdomen and chest present or absent (may be broken to long segments); pale fins, with upper and lower margins of caudal fin with a broad brown band, darker at base; when fresh, noteworthy are the many small yellow spots, and the lack of blue spots - blue only between yellow markings around eye.
