The carp is generally considered the largest of the minnow family, although the pikeminnows, or squawfishes, of the Columbia and Colorado rivers average 30 lb (13.5 kg) and the mahseer, a game fish of India, is also large. However, most minnows are small. They have great importance in the cycle of freshwater aquatic life, since they consume aquatic insects, larvae, and crustaceans and in turn serve as food for many larger fish. Most species are dully colored, though a few are brilliantly hued in greens, reds, and yellows.
Various members of the family are called shiners, chubs, daces, roaches, breams, and bleaks; many of the American species are called shiners. The most widespread American minnow is the common shiner, Luxilus cornutus or Notropis cornutus. The Eurasian minnow is Phoxinus phoxinus. The creek chub and the golden shiner, a greenish fish that turns golden during the breeding season, attain a length of 12 in. (2.5 cm). The red shiner and redbelly dace are also named for the seasonal color changes in the male. The goldfishgoldfish,

The carnivorous mudminnows of the family Umbridae, found in the sluggish waters in the Great Lakes region and the Atlantic coastal lowlands, superficially resemble toothed minnows but are more closely related to the pikepike,

Minnows are classified in the phylum ChordataChordata
