A baby fish is called a fry. When fish hatch from their eggs, they are typically very small and are referred to as fry. As they grow and develop, they go through different stages, but the term “fry” is commonly used to describe young fish that have recently hatched.
During the fry stage, the young fish are usually still dependent on their yolk sac for nutrition. As they mature, they start to feed on small organisms in the water. The term “fry” is used across various species of fish, making it a general term for young fish in their early stages of life.
