When potential predators come near the shoal, some common minnows take the risk of approaching the predators in order to inspect the predator and assess the danger. Predator inspection behavior increases the risk of being attacked and eaten by the predator, but the behavior is beneficial to the inspectors as more alert minnows react more ...
The northern redbelly dace has a direct economic value to humans as it is a popular baitfish used by many anglers across Ontario. Furthermore, as a minnow it is a primary consumer that feeds on algae. As such, it provides food to predators, particularly large fish and water fowl, which are game for fishers and hunters. [7]
Fathead minnow (Pimephales promelas), also known as fathead or tuffy, is a species of temperate freshwater fish belonging to the genus Pimephales of the cyprinid family. The natural geographic range extends throughout much of North America, from central Canada south along the Rockies to Texas, and east to Virginia and the Northeastern United States. [2]

Sometimes it competes with other sucker species and redhorse for breeding habitat. During the egg-laying process, daces, minnows, and chubs will sometimes forage on the freshly expelled eggs. [3] Spawning takes place in shallow water riffles usually during May, when the water temperature is about 15 °C (59 °F).
Bluntnose minnows are commonly 6.5 cm (2.6 in) long, with a maximum length of 11 cm (4.3 in). On the first two or three dorsal rays are dark pigmented spots. The scales between the head and the dorsal fin are noted to be smaller than the rest of the scales on the body. [3]
These minnows have a pair of pectoral fins, along with a pair of small pelvic fins. [8] The Mississippi silvery minnow, like many other minnows, have an anal fin, dorsal fin, and a powerful caudal fin. The dorsal fin is very centered between the head and the caudal fin. All fins on the fish have no makings and are transparent.
With over 300 known species, there are more species of minnows native to North America's fresh waters than any other fish. [2] Minnows can be hard to distinguish because many look alike. [3] All minnows have one dorsal fin, ventral fins near the anus, a lateral line system (in most species), and smooth, round cycloid scales. [4]
