In the rivers, lakes, and coastal waters of the USA, tiny fish like minnows, shiners, and anchovies may seem small, but they play a vital role in the ecosystem. These little fish are the foundation of many food chains, providing food for larger fish, birds, and marine mammals. By living in large groups, they help maintain balance in nature, ensuring predators are fed and other species remain healthy. Despite their size, these fish are crucial for the survival of many creatures and the overall health of aquatic environments, supporting both nature and the fishing industry.
