To feed minnows the kind of food they'd eat in the wild then you need to give them food like small bugs (like flies and mosquitoes), as well as pieces of dead plants and even animal matter. This is the kind of things that minnows eat in the wild and this is what they thrive on, food-wise. In the saltwater regions, however, the minnow fish will eat a better diet of shrimp. These are generally not things that those who have minnows want to feed to their fish, and hence aquariums can sell freeze dried food and blood worms that you can feed to your minnows to make the whole process much easier.
One other option for minnow owners is to simply feed the minnows tropical fish flakes. Goldfish flake food works, too! Some minnows are pickier than other minnows, however, and will sometimes turn their nose up at flake food. You can try feeding the minnows, in this case, on 50% brine shrimp and 50% flake food until they eventually become accustomed to it.
No matter how long you are keeping your minnows for, you must remember that the most common cause of death for the fish is actually overeating. This means that at all times you should be feeding them the right amount of food every single day. Whenever you feed the minnows, you need to ensure that the pieces are relatively small. You can start off by feeding them a small amount of food. Then, after around five minutes, all the food should have disappeared from the top of the tank and there should not be any of the food resting at the bottom of the tank. If after five minutes, however, there is food at the bottom of the tank then you need to reduce the amount that you are giving your fish.
