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.
You can add all sorts of pond plants to a turtle's tank or pond and find out what they do and do not eat. Turtles that are inclined to eat plants will eat most floating plants like duckweed, azolla, frog-bit, water hyacinth, and water lettuce. Most submerged plants are also eaten like anacharis. It is said that most turtles will not eat cabomba. Lily leaves are relished so do not put expensive ones in with turtles.
