Minnows are small freshwater fish that belong to the family Cyprinidae. They are often found in rivers, lakes, and ponds, where they swim in schools. These tiny fish usually measure just a few inches long and are known for their slender bodies and shiny scales. Minnows play an important role in the aquatic ecosystem, serving as food for larger fish and other wildlife. Many people enjoy observing minnows while fishing or exploring nature. They are also popular in home aquariums, where they can add color and movement. Some common types of minnows include fathead minnows and rosy red minnows, which are often used as bait by anglers.
