The inland silverside is a member of the New World silverside family. Its first dorsal fin originates far in front of the anal fin’s origin, and this species lacks a lateral line. It has a sickle-shaped anal fin. Inland silversides can be found in lakes and quiet areas of streams, usually swimming in schools at the surface.
