Tortoises shed their shells. Shelling is also called shell changing, which is its normal physiological behavior during its growth. Usually, different species of turtles have different shell changing cycles. In artificial rearing, nutrition should be supplemented during shell changing, especially calcium should be sufficient, so as not to affect the development of new shells. In addition, we should pay attention to cleaning and keep the environment clean, so that it is not easy to get sick. Don't disturb it during shell changing, lest it be frightened.

1. Supplementing nutrition: First of all, turtle should pay attention to supplementing nutrition during shell change. Because the main component of turtle shell is calcium, it needs to be supplemented with calcium. There are many ways to supplement calcium, such as adding calcium powder to food and feeding some egg shells. In addition, the absorption of calcium can also be promoted by basking in the back.

2. Cleaning: Because shell changing is not disposable and needs a little change, there are often some fragments in the feeding container, so it is best to clean them out during cleaning to avoid polluting the water quality. And keeping a clean and hygienic environment is also very helpful to the health of turtles.

3. Avoid disturbing: In order to ensure that the turtle can change its shell safely, it must not be disturbed during the period, and no artificial help should be given, because it is easy to cause the turtle to be injured, and even be infected by bacteria, thus causing the turtle to get sick. If you want to help, you can brush a little with a soft toothbrush.
