The Tule perch is a small native fish species that lives in the great central valley of California. It can reach lengths approaching ten inches long. With a pointed snout and small mouth, the Tule Perch feeds primarily on small insects, mollusks, and crustaceans. This is the only freshwater member of the family Embiotocidae, which includes the saltwater shiner perches and surfperches. All are viviparous, meaning they give birth to live young. Different populations of Tule Perch may have different markings, including stripes, spots, or a "clear" or silvery color phase. In some cases, several different color morphs may occur within the same population of Tule Perch.
