Reclaim your pond from mosquitoes — naturally. These 12 Texas-native Mosquitofish (Gambusia affinis) eat up to 80-100 larvae per fish per day. No chemicals. No sprays. Just fish doing what they do best. Compatible with koi and goldfish. Self-sustaining — females give birth to live fry monthly. Locally sourced and available for same-day or next-day delivery in the DFW area. Recommended for ponds up to 10 sq ft of surface area.
