Under normal circumstances, a young turtle needs a certain amount of room to move, about five liters of water, and the depth of the water is kept within the length of the turtle, so as not to pass over the turtle's head as much as possible, so that the turtle can stand on tiptoe without touching the bottom when breathing. If it is an adult Brazilian turtle, it needs a larger range of activities, more than ten liters of water. Although the amount of water generally does not affect the life safety of turtles, the water level should be strictly controlled. Pay attention to changing water when raising turtles, and change water diligently. After each feeding, the turtle will defecate, and then it can pour out two-thirds of the water and inject new water, or don't feed in the water. Proper sunshine for turtles is beneficial to their growth. But don't do it at noon, when the sun is too sunny. Just do it in the morning for 15-40 minutes.
