Size 150mm or 5.9" SL. Find near, nearer or same sized spp.
Identification 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.
Sexing Males sport conspicuous odontodes along the sides of the head and rostrum.
General Remarks This is probably the most common Sturisoma shipped from Colombia.  Sturisomatichthys leightoni are often mixed in the shipments.  These shipments are also sometimes combined with shipments of another Sturisoma species that are collected further downriver.
