Description
Gymnotus anguillaris is an eel-like freshwater knifefish of the family Gymnotidae in South America. The body is elongate and laterally compressed, lacking a dorsal fin, with a long anal fin that propels the fish by undulating movements.

It inhabits swamps and creeks with moderate flow and a bottom covered with vegetation or plant debris, hunting at night for aquatic invertebrates, insect larvae and crustaceans. The species is relatively aggressive and lives in small groups.
