water all the time, because they are terrapins themselves. In the wild, they can hardly climb to the shore except for breeding, so staying in the water all the time will not affect their health. But the best way to raise snapping turtles at home is to build a drying platform for them and not let them live in the water for a long time.
Because exposure to the sun can promote their synthesis of vitamin D and kill most of the bacteria on the carapace. But snapping turtles are different from other shallow terrapins. They can't stay out of the water for too long, so they should control the time of basking in the sun, not more than one hour at most, otherwise they will be dehydrated.
usually change water once every three days. If the container for raising snapping turtles is large and the water level is deep, it can be changed once a week. If there is a filtration system, the frequency of water change can be further reduced. But it depends on the water quality. If the water quality deteriorates quickly and the water smells sour, it needs to be changed immediately. If the water is clean and fresh, the water change time can be extended for several days. If you raise snapping turtles in shallow water, change all the water. If you raise it in deep water, you can change half or one third.
