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.
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.

IUCN Red List Category	Data Deficient, range map and more is available on the IUCN species page. Last assessed 2014.
pH	6.6 - 7.6
Temperature	20.0-26.0°C or 68-78.8°F (Show species within this range)
Other Parameters	Soft to medium water hardness. It should also be noted that this fish prefers slightly cooler water and may not thrive in a warmer (over 78°F/26°C) aquarium.
Husbandry Information
Feeding	Typical of the genus. The diet should be mainly spinach, cucumber, and algae wafers with meaty food like blood worms or brine shrimp fed once per week.
Furniture	Does well in a planted aquaria with driftwood.
Compatibility	Peaceful community fish. Do not place with more robust loricariids as it is not a strong competitor for food.
Breeding	See Shane's World article.
