The common gambusia is a small freshwater fish up to seven centimeters long. It actively eats mosquito larvae and other small aquatic animals.
Gambusia differs from most fish in that it gives birth to live fry rather than laying eggs. It is important for nature because it significantly reduces the mosquito population in water bodies.
Immature form that undergoes metamorphosis before adulthood.
