Do minnows live in the ocean?

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.
