• Mosquitofish are visual predators and primarily feed during the day. If the water is covered, they can also detect prey through vibrations.
• Female mosquitofish are 2-3 inches long when fully developed; male mosquitofish are 1- 1.5 inches long.
• Young fish, also known as fry, are ready to eat mosquito larvae immediately. Mosquitofish also can eat plankton and aquatic insects.
• Mosquitofish have been introduced to more than 60 countries on nearly every continent.
