Behavior of the Mahi Mahi

These fish have incredibly active behavior and must swim constantly to push water through their gills. They spend much of their time hunting for prey, and have generalist feeding habits, which means that they eat anything that they can swallow. Some live solitary lives while others live in schools.

Reproduction of the Mahi Mahi

These fish begin breeding when they reach four or five months old. In tropical regions these fish breed year-round. They reproduce via spawning, where the females release their eggs and the males fertilize them outside of the body. A single female can produce up to a million eggs. The adults do not protect the eggs or larval young in any way.
