Arizona Aquatic Gardens is one of the largest suppliers of farm-raised Mosquito fish in the U.S. for county vector control agencies. This environmentally important fish is used for controlling mosquitoes and their larvae. Mosquitofish are sold commercially through our company from just small quantities for small ponds, livestock water troughs, and more to massive quantities for government mosquito control programs, Vector Control, golf courses, HOA Ponds, and other wetland restoration projects. 

The Male Mosquitofish is smaller than the female. When they are young, it’s hard to tell boys from the girls though. As they get older, the female will always grow larger than the male, and since this is not an egg laying fish, but rather a “live-bearing” animal, the female may have what appears to be a balloon belly from time to time just before birthing frye…… because she is “pregnant”.

Are mosquitoes taking over your pond? Regain control with the world’s best mosquito eating fish from Arizona Aquatic Gardens. Gambusia affinis (often referred to as “mosquito fish” or “mosquitofish”) have been used for mosquito control in the United States since 1915. These fish are vivacious consumers of mosquitoes, mosquito larvae, mosquito pupae, and other flying insects and larvae, and can survive varying water conditions.
