The razor turtle changes its shell. Because with the continuous growth of razor turtles, their bodies will get bigger and bigger, and their shells may limit their growth, so they need to be changed constantly to adapt to the continuous growth of their bodies. The time for them to change their shells is not fixed. Sometimes they can change their old shells in a few days, but sometimes they may take a month to finish.

Regular cleaning of the tank residue is required during their shell change. Because razor turtles need a clean environment, this can reduce their chances of infection. When changing shells, their bodies are weak. If the water quality is poor, they may get sick. Therefore, it is necessary to change water regularly to ensure good water quality and environment. At the same time, attention should be paid to fishing out their old shells from the fish tank to avoid polluting the water quality.

The shell of razor tortoise grows fast. The growth rate of turtle shells is related to the environment in which they grow. If the water quality is better, their growth rate will increase. Under normal circumstances, their shells can grow well in half a month. In the meantime, care should be taken that razor turtles are not infected, otherwise their wounds will take longer to heal. During shell changing, they should also be fed more high-protein food to promote turtle shells to heal faster.
