The turtle food fed by yellow-headed side-necked turtles in a day can be determined according to their body shape. Generally speaking, the amount of turtle food fed is the best in two-thirds of the head size. Although turtle food has comprehensive nutrition and can replace staple food, turtle food is not easy to digest and cannot replace staple food for a long time, so it is best to feed it with other foods.

Yellow-headed side-necked turtles like plant feed, and breeders can feed them more cabbage, cabbage, water spinach, oilseed vegetables, apples, bananas, grapes and so on. It is also necessary to match some small fish, shrimp, loach, tadpoles and other foods to ensure their balanced nutrition.

How often the yellow-headed side-necked turtles are fed depends on the feeding environment and their growth stage. If they are young yellow-headed side-necked turtles, they need to be fed once a day, because they have a high demand for food at this time, so breeders should feed more food to ensure their adequate nutrition. When they are adults, their bodies are no longer developing, and they don't need much food, so they can be fed once every 2-3 days.

If the temperature is high, their metabolism will be accelerated, and breeders need to feed them once a day. If the temperature is lower, their appetite and activity will decrease, and breeders need to reduce the frequency of feeding.
