The orangefin tetra (Bryconops affinis)[1][2] is a small species of freshwater fish from South America that belongs to the family Iguanodectidae. Though common in its native range, it seems to prefer fast-flowing and shallow creeks. It is an active swimmer that feeds on plant material and various invertebrates, sometimes jumping out of the water to catch prey above the surface.
It has a peaceful demeanor, living in schools and inhabiting the same areas as various other fish species. When it spawns, it prefers environments with plentiful vegetation. Its eggs are adhesive, and are released in batches instead of all at once.
It looks quite similar to one of its congeners, B. melanurus, hence the specific epithet "affinis" (which means "close to"). Another common name is "orangefin characin", but this is inaccurate; a characin is any fish of the family Characidae, and the orangefin tetra belongs to the family Iguanodectidae. However, it used to be classified as a member of Characidae, so the name is not outright incorrect, just outdated.
