Minnows are small fish often used as live food for certain reptiles, including aquatic snakes, turtles, and some lizards. They are rich in protein and essential fatty acids, providing a source of energy and nutrients for carnivorous reptiles.
 As a live food, minnows stimulate reptiles' hunting instincts, which can be beneficial to their well-being. They can be fed fresh or frozen, but it is important to ensure they come from safe, uncontaminated sources.
