grass turtles need water. They belong to water turtles and usually live in water. Although they can move on land for a short time, in fact, they live in water most of the time. If they leave water for a long time, they may suffer from heatstroke, dehydration and death. Also, when they grow in the wild, they all move in streams, rivers, lakes and other places, so they need water to raise them. When raising grass turtles artificially, it is necessary to build an amphibious environment for them, which can simulate the wild environment, and they can choose their own living environment.

It is best for grass turtles to be raised in shallow water, because they are not pure water turtles, and their water quality and swimming ability are not very strong, so they cannot adapt to too deep water level. If the water level at which they are raised is too deep, choking and drowning may occur.

The height of water level can be adjusted according to their body shape. Normally, the water level of young grass turtles can be controlled below the carapace. Because the grass turtles in their infancy have poor physical strength, they can't swim from the bottom to the water quickly. As they grow in size, the water level of breeding can also increase, and the height of water level can be 1-2 cm higher than that of carapace. When they reach adulthood, the water level can be twice the height of their carapace.
