Bryconops alburnoides is a small freshwater fish, approximately 6 inches long at its largest, that lives in the rivers of South America.

It has a slender body, with a yellowish dorsal fin and yellow-tinged back scales that fade into silver on its belly.

It is largely an insectivore that picks land-dwelling insects from the riverbanks, though it eats much more whenever rain washes prey into the water.

Bryconops alburnoides reaches 15 cm (5.9 inches) at a maximum in standard length (tail fin not included), with a generally elongated body.

[4] A congener, Bryconops gracilis, has frequently been misidentified as B. alburnoides, thanks to a yellowish dorsal fin and a similar number of lateral-line scales.

[7] Research from Oliveira et al. prompted Bryconops, along with sister genera Piabucus and Iguanodectes, to be moved to the family Iguanodectidae in 2011, which was revived from the work of ichthyologist Carl H.

Like the rest of the genus Bryconops, B. alburnoides is found solely in South American freshwater habitats.
