Bryconops
''Bryconops'' is a genus of freshwater fish in the family Iguanodectidae from South America. It consists of small fish, all under half-a-foot long, with slender bodies and silvery scales, though there is some mild color variation.

Many ''Bryconops'' prefer clearwater environments with a strong current, though some are partial to slow-moving Blackwater river, blackwater, and several are endemic to their locale. The majority of species are from Brazil or Venezuela. Rivers and river basins that house species of ''Bryconops'' include the Tapajós, Tapajos, Orinoco, Tocantins River, Tocantins, Rio Negro (Amazon), Negro, and Madeira River, Madeira. Few species of ''Bryconops'' have been evaluated as far as conservation status, but most of them are believed to be low-risk species. The greatest thr ...

Description ''Bryconops durbinae'' is small and slender, with a large mouth in comparison to the body. It is the smallest member of the genus ''Bryconops'' at 3.1 cm (1.2 in) in standard length; the second-smallest is ''Bryconops disruptus'', at 6.4 cm (2.5 in). Its fins are generally hyaline (transparent), though it does bear a caudal ocellus (eyespot on the tail) that is transparent when preserved in alcohol, but ranges from red to yellow in life. Its caudal fin is darker than the rest, which makes said ocellus more obvious upon examination. In terms of body coloration, ''Bryconops durbinae'' is generally an Iridescence, iridescent silver, with a black lateral stripe down each side underlined by a silver ...
