Young Sturisoma of any species are difficult to distinguish. S. aureum can be distinguished from most congeners by the black horizontal markings behind the first dorsal ray, that are solid vice speckled. It also appears to be the smallest member of the genus rarely reaching over six inches in length. S. aureum, when in good condition, has a long trailing fin extension from the upper caudal lobe.
Males sport conspicuous odontodes along the sides of the head and rostrum.

头扁吻宽,口向下,口唇发达如吸盘,唇角两端各有一根触须。体形呈流线形,细长腰,有鞭尾,体表呈黄金到土褐色,体侧有大区域的黑色斑驳。底栖性,常栖息于河流湲流区岩石底部或沙质底土处。喜夜行和弱旋光性,触须兼有触觉和味觉功能。杂食性,对蠕虫、腐肉、水生昆虫和藻类有偏好。可当食藻鱼来饲养。会刮除消化沉木表皮,饲养可放入沉木供栖息
