* Insects: Larvae, nymphs, and adult insects are a common food source for lungfish.
* Crustaceans: Crayfish, shrimp, and other crustaceans can be part of their diet.
* Small fish: Lungfish will eat smaller fish species, especially if they are young or injured.
* Amphibians: Some lungfish will eat frogs, tadpoles, and other amphibians.
* Worms: Earthworms and other aquatic worms are readily consumed by lungfish.
* Plant matter: While primarily carnivorous, lungfish will also eat plant matter like algae and decaying leaves.
It's important to note that larger lungfish may also prey on larger animals like snakes, turtles, and even small birds.
Overall, lungfish are adaptable feeders who take advantage of whatever food sources are available in their environment.
