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.
In the wild, they feed on fish, crayfish, tadpoles, a variety of aquatic invertebrates and a wide range of aquatic plants including duckweed and watercress (Cohen, 1992). Young painted turtles are carnivorous, eagerly consuming fish, worms, crickets, and floating turtle food. As they grow, they become more herbivorous and adults seem to enjoy water lettuce, water hyacinth, and duckweed in addition to romaine lettuce, kale, and other greens.
