I don't know where you live but if it's possible to put a 5 gallon bucket outside away from the house and fill it with water, mosquitoes will lay their eggs in there. They start a new colony every 7 days. Get yourself a fine mesh net and a bowl. Go out and check your bucket in about 2 weeks. If you see mosquito larva in there scoop some out quickly before they swim to the bottom. Fill the bowl with tap water before going outside and put the larva in your bowl. Rinse your net off from a hose if you have one. Pour the mosquitoes Bach through the net to strain them. Put more water in your bowl. Maybe an inch deep and put the mosquito larva back in there. Slowly pour the water with the larva into your bowl. Allow only a few at a time and make sure the fish eat them before adding more. Once you feel the fish are full, stop feeding them the larva. If any left over larva, pour them in a zip lock baggy and freeze them. You can drop the ice and all into your tank if it isn't a huge chunk of ice or thaw and pour again when ready! Mosquito larva gives your fish a good hunt, it's very nutritious and they are free! Remember though, don't just dump the larva into your tank all at once. If some are missed, in a few days the larva will turn into biting adults and you don't want them flying in your home. I feed these once a day every day and then feed my fish flake food later in the day. My fish are thriving!! They breed like bunnies, they grow larger and meatier and they are so colorful and healthy!
