The bottom shell of the turtle is also normal, indicating that it is changing its armor. Changing armor is a normal physiological activity of turtle. When it reaches a certain age, it will start changing armor. Nail change lasts for a long time, so we must pay attention to supplementing nutrition during the period. In addition, it is best to clean up the fallen nail pieces in time, so as not to affect its health. Don't help people when changing armor, otherwise it may be hurt.

1. Supplementing nutrition: During the shelling period, turtle needs to supplement enough calcium, which will help it change its nail. At ordinary times, you can feed fresh fish and shrimp, not just turtle food, but also some vegetables, so as to ensure balanced nutrition. Usually feed it once every three or five days, and don't eat too much each time.

2. Improve the environment: When changing armor, the turtle's body is still very fragile, so it is necessary to ensure that there is no threat to its living environment. If there are stones or shells in the jar, it is necessary to take them out in time to avoid touching it. At the same time, it is necessary to control the water level, just after passing the back.

3, don't help: When turtles change their armor, they must not help artificially. If they accidentally cause tortoise shell damage, it will take a long time to recover.
