Eigenmannia is a genus of fish in the family Sternopygidae (glass knifefishes) native to tropical and subtropical South America (south to the Río de la Plata Basin), and Panama.[1][2] They are typically found in slow-flowing streams, along the edge of large rivers, in deep river channels and in floodplains, and the genus also includes E. vicentespelaea, the only cave-adapted knifefish.[2][3] Eigenmannia are often found near submerged roots, aquatic plants and floating meadows.[3][4]
Depending on the exact species, they have a maximum total length of 12–48.6 cm (5–19 in).[1] They are nocturnal, and feed on small invertebrates such as aquatic insect larvae and zooplanktonic crustaceans.[3]
