If the fish are an Estuarine species it is possible that they could be slowly and gently converted to live in fresh water. They would however die of shock if they are taken from salt water and suddenly placed in fresh. If they are true marine fish from the Ocean, then they will never live in fresh water no matter what you do.
Minnows typically do not live in the ocean; they are freshwater fish found in rivers, lakes, and streams. However, some species of minnows can tolerate brackish water, which is a mix of fresh and saltwater, and may be found in estuaries where rivers meet the sea. Generally, true minnows belong to the family Cyprinidae, which is primarily associated with freshwater habitats.
