What is the body structure of a betta fish?

The body structure of a betta fish features a laterally compressed shape, which allows for agile movement in the water. They possess a small, elongated body with a large head and long, flowing fins that vary in shape and size between different breeds. Their scales are often vibrant and iridescent, contributing to their striking appearance. Additionally, bettas have a specialized labyrinth organ that enables them to breathe air, allowing them to thrive in low-oxygen environments.
