How long does it take for a fry to grow?

The time it takes for a fry to grow into an adult fish varies depending on the species of fish. Some fish, such as guppies, can reach maturity in as little as 3-4 months, while others, such as certain species of cichlids, may take up to a year or more. The growth rate of a fry is influenced by several factors, including water temperature, food availability, and the species' genetic potential.
