Food and feeding
Mosquito fish are perfectly happy to eat anything offered. Quality flake should provide the staple diet but they will also nibble at plants.
Central America; Mosquito fish are native to the Gulf of Mexico.
Females will grow up to 2.5 inches in length; males will only grow to 1.5 inches in length. As with most livebearers, the male has a modified anal fin that has taken a pointed appearance.
Females will store the sperm for up to 2 months and can produce several batches of fry from this. Keeping them in a planted tank will provide the fry with hiding places, away from predators. In the wild they are prolific breeders.
The expected life span for Gambusia affinis is 2-3 years.
Mosquito fish have a reputation for overpopulating areas when introduced to them. Never release these fish in the wild as they will take away the food supply from other aquatic dwellers. Gambusia affinis can tolerate a wide range of temperatures; some keepers will even keep them in outdoor ponds.
