The Interplay of Genetics and Habitat

The size of a Betta fish is not merely a matter of chance; it’s the result of a complex interplay between genetics and the environment.

The environment, however, plays an equally pivotal role. The conditions in which a Betta fish is raised can significantly influence its development. Factors like tank size, water quality, and nutrition are crucial.
