Acrossocheilus iridescens is a species of cyprinid fish native to freshwater in southeastern China, northern Laos, and northern Vietnam.[1] It reaches up to 29.7cm (11.7inches) in standard length. Juveniles are pale yellowish with 5–6 narrow dark bars, but in adults (over 11abbr=onNaNabbr=on long) the dark bars are broad.[1] It has sometimes included A. longipinnis as a subspecies, but recent authorities recognize them as separate species.[1]
