Down arrow Species Information
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 Evers and Seidel (2002) describe this fish in earlier editions of their Wels Atlas as Sturisoma sp. "Kolumbien". 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.
Down arrow Habitat Information
Distribution Colombia.  Found in the Rio Magdalena and its tributaries, upstream of Honda. It appears to be the species common in the upper Magdalena and is replaced downriver by another Sturisoma species.
Magdalena, San Jorge and Cesar River basins, Colombia.
