Here's some info from Fishes of Tennessee by Etnier and Starnes - "...quite
pelagic in it's habitats and occurs in lakes, reservoirs, big rivers, and
occassionally enters mouths of smaller creeks. ...Food consists primarily
of zooplankton, midge larvae and pupae, algae, and adult insects (lakes and
reservoirs) and adult aquatic and terrestrial insects and aquatic insect
immatures in rivers. Spawning is reported to be at night, often in large
schools, in 2 to 6 meter depths over a variety of firm substrates, and
occurs from late spring through mid August, but is concentrated between
late May and early July in Tennessee. The 2000 to 3000 eggs produced by
each female are reported to harch in 24 to 32 hours. Sexual maturity is
probably reached during the first year, and life span is three years.
Widely used as a bait minnow, although difficult to keep alive in warm
