Spatuloricaria gymnogaster

Spatuloricaria gymnogaster is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the upper Magdalena River basin in Colombia.

FishBase records a maximum standard length of 370 cm for the species, but this is unlikely and can be assumed to be a misprint, with 37.0 cm being the actual upper bound stated in the reference cited. Some sources list a standard length of 25 cm for Spatuloricaria gymnogaster, and FishBase provides a maximum weight of 235.3 g.
