How to identify Mosquitofish

Mosquitofish are small fish with gray bodies and prominent abdomens. Both their dorsal and caudal fins are round, and their mouths resemble an upside-down smile. Mature females are generally larger than males, often reaching almost three inches long, while males only reach up to 1 ½ inches long. The dorsal fins in female mosquitofish are similar than the anal fins. Males, on the other hand, have distinct, pointed anal fins.

Where to catch Mosquitofish

Mosquitofish are present throughout the world in areas where they were introduced as a natural way to control high concentrations of mosquitoes. Unfortunately, this introduction has had a negative effect on those ecosystems. These fish are found in shallow waters of the Gulf Coast, northeast Mexico, along the Mississippi River, southern Illinois, and in southern Indiana.
