The long-bodied snake-necked turtle is a vegetarian tortoise, feeding on various plants and fruits. Juvenile snake-necked turtles are especially fond of watermelon, strawberries and tomatoes. Usually long-bodied snake-necked turtles do not like to sunbathe, but prefer to hide under dead trees or dead leaves, so long-bodied snake-necked turtles do not need strong light or heat preservation lights.

Long-necked turtles are usually herbivorous under natural conditions , although the long-necked turtles sometimes eat meat in captivity. It is best to feed the snake-necked turtle a jaggery consisting of fruits, vegetables, and kale leaves two to three times a week. Feed skinned and minced mice or flesh-colored juveniles every two weeks for grown-up turtles, but do not feed juveniles and juveniles with meat. Most juveniles and juveniles prefer tomatoes more than any other food, and tomatoes are the best option for those picky eaters to eat regularly.

The snake-necked turtle in the wild feeds on plants and animals. Lives in shallow water and occasionally climbs on land. In the dry season, they hid in the mud of the pond and dormant until the rainy season. It is a very useful animal for people because it eats the larvae of a large number of mosquitoes.
