Its wavy lateral line is strongly curved downward, accentuated with two rows of black spots and a dark stripe.
Juveniles can be identified early by their thin black line along the back.

The schneider is a fish living in schools that naturally resides at mid-depth and close to the surface. It is a species with a lively temperament. This species is very active by nature and enjoys large spaces.
It is capable of undertaking long migrations in early and especially late summer and does not hesitate to use fish passages in large numbers. Its potential predators are trout, chub, perch, and zander.

The species particularly favors clear waters with strong currents and rapids in the barbel zone, but can also be found in the cool waters of some alpine lakes.
Primarily insectivorous, it often feeds in open water on organisms carried by the current. It may supplement its diet with algae (diatoms, chlorophytes, etc.). The substrate is generally composed of pebbles and rocks.
