Western pond turtles are omnivorous and most of their animal diet includes insects, crayfish and other aquatic invertebrates. Fish, tadpoles, and frogs are eaten occasionally, and carrion is eaten when available. Plant foods include filamentous algae, lily pads, tule and cattail roots.
Most pond fish eat insects such as mosquito larvae and fish eggs because they also need protein sources in order to survive. Pond fish such as koi eat water vegetation. However, because too many plants can choke the life out of a pond, limit the introduction of excess vegetation.
