Crocodile turtles are water turtles and like to live in water, but they don't have too strict requirements on the water they raise. Normally, they are more suitable for living in rivers and lakes. Because they lived in streams, rivers, lakes or swamps when they were in their original places, it is most suitable for their habits to breed them with river water. However, in the current environment, rivers and lakes are easily polluted, so breeders need to filter impurities in advance before using them. Moreover, river water and lake water are not easy to obtain now, and breeders can choose to use tap water for farming.

Although tap water is easily available, it contains a lot of chlorine gas, so breeders need to expose it to the sun for 2-3 days before giving it to crocodile turtles.

The water level required by different stages of crocodile turtles is also different. It is best for the water level of crocodile turtles in infancy to be consistent with the height of their carapace, so as to neither affect their carapace development nor their respiration. As they grow in size, the height of water level can also be raised. When they are adults, the height of water level can be controlled at 2-3 times the height of carapace. If they are given a balcony or gentle slope, the water level can be raised relatively.
