The dead leaf turtle is carnivorous, mainly feeding on aquatic invertebrates, worms, snails, shrimp and fish, as well as the stems and leaves of plants. Usually they are active in shallow water. The nose of the dead leaf turtle can breathe through the water surface. It is very easy to feed. You can feed live fish, shrimp, and tadpoles. Do not feed goldfish. This will endanger the health of the dead leaf turtle. Change recipes, and try not to feed thawed small fish.

The dead leaf turtle has the habit of preying at night. Foods include fish, amphibians, freshwater shellfish, or fallen birds and small mammals. The dead-leaf turtle's predation method is unique among turtles, and they remain still in the water, allowing them to blend into their surroundings. Until the fish approaches, suddenly extending its head close to the prey, while opening its mouth and widening its throat. This set of movements creates a pumping action that sucks the prey into the dead-leaf turtle's enlarged throat, the water is expelled, and the prey is swallowed. The dead leaf turtle eats this way because it cannot chew.
