Mosquito Fish

Mosquito fish are very suited to the pond but can be fin-nippers in the aquarium. These small livebearers are about the best fish a pond keeper can get to keep mosquitoes from ever being established in the pond. An assortment of ten will be a nice breeding clan to get these pond fish established.

Quick Facts

Care Guide

Tank setup: Mosquito fish are very hardy and do fine at room temperature without a heater. They also do well in outdoor ponds, where they eat mosquito larvae. Keep a lid on the tank.

Feeding: Feed a quality flake once or twice a day, only as much as they eat in a couple of minutes. Outdoors, they also eat insects and mosquito larvae.

Tankmates: Mosquito fish can be nippy, so keep them with other hardy, fast fish rather than slow, long-finned fish.

Breeding: They are livebearers and breed easily. Adults will eat the babies, so thick plants give them a place to hide.

Good to know: Mosquito fish are livebearers and breed quickly in ponds, which is why they are so good at keeping mosquitoes under control.
