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.

Great for controlling mosquito larvae in my pond. The fish are active and easy to care for. I noticed a significant reduction in mosquito populations after introducing them. Just be mindful of other fish with long fins.

Ordered a pack of ten and they arrived quickly. The fish are healthy and have started reproducing. They’re a good choice for pond owners looking to naturally reduce pests.
Madeleine Miller –
They work well in the pond but I did see some fin damage to smaller fish in the same tank. Not ideal for mixed community tanks.
