There are two types of Mosquitofish, the Western Mosquitofish (Gambusia affinis) and the Eastern Mosquitofish (Gambusia holbrooki). They are both quite small the females reaching only 2-1/2" and the males 1-/2". These fish are grey with a mouth that is permanently pointed upwards to feed off the water's surface.
Mosquitofish can reproduce quickly with a female reaching sexual maturity in under 9 weeks. They can produce almost 100 young at a time! Even though they only live to about 4 years maximum, they manage to multiply and take over places that they are introduced to. The numbers suggest that they can expand from 7,000 to 120,000 in just five months! As you can imagine these species can easily become an invasive species, but their uncanny ability to eliminate Mosquitos still makes them a popular fish! They are even often kept in an aquarium setting!Subject Replicated
