Yellow-headed side-necked turtles like to eat aquatic plants. When they are in the wild, they all live on aquatic plants, algae and plants in water. Although they are omnivorous turtles, they prefer plant-based feed, so aquatic plants and algae in the water are their favorite food. If the yellow-headed side-necked turtles are farmed artificially, it is best not to raise them with aquatic plants, otherwise the aquatic plants will probably be eaten up by them, and they may pull out the roots of aquatic plants. It is best to raise the yellow-headed side-necked turtle in bare tank. If there are aquatic plants in the fish tank, you can usually feed more tender leaves of vegetables to ensure that they have enough food and avoid eating aquatic plants.

Yellow-headed side-necked turtles prefer plant feed, and breeders can feed them more vegetables, fruits and other foods. Although they don't like animal feed, breeders should give them a small amount of food regularly to ensure their adequate nutrition.

The yellow-headed side-necked turtle in its infancy has a large demand for food, and the proportion of animal feed fed by breeders can also be larger. When they no longer grow in size, they can reduce animal feed and add more plant feed. If breeders don't have time, they can use synthetic feed instead of staple food for a short time, but they can't feed for a long time.
