The general background color is dark brown on the head and trunk, transitioning to beige or light brown on the muscular part of the tail. The body is finely stippled with bright iridophores over the dark background. Dark brown pigmentation extends from the trunk onto the muscular tail, forming approximately a dozen diffuse dark blotches along the tail. Red gills and heart are faintly visible through the translucent ventral skin, with a patch of iridophores covering the heart. The skin below the gills is stippled with iridophores. The abdomen is opaque silver with a distinct midline streak, and gut coils are covered ventrally by a silvery iridocyte sheath. Tail fins are mostly clear, with scattered melanophores and iridophores. Major lateral tail vein and some myosepta are discernible.
