Different crocodile turtles have different living water levels, so it is best for breeders to control the feeding water level according to their body types. Under normal circumstances, the water level of newborn crocodile turtles is shallower, and the height of water level can be consistent with the height of carapace. Because crocodile turtles are just born, their physical strength and swimming ability are poor, so they need a shallower water level to survive normally. As they grow in size, the height of water level can be controlled to double the height of carapace.

When they are mature, the breeder can stabilize the water level at 2-3 times the height of the carapace. Because deep water can make their carapace develop better, and there is more room for movement. If the breeder builds a balcony or gentle slope for them, the height of the water level can be raised, so that they can freely choose the water level of their life.

The temperature in the origin of crocodile turtles is relatively high, so they also like to live in deeper water temperature. During artificial breeding, the water temperature can be kept between 20-33 ℃, and if conditions permit, the water temperature can be kept between 25-28 ℃. In this temperature range, their appetite and activity are the highest, so their growth and development speed is also the fastest.
