Compared with other turtles, yellow-headed side-necked turtles grow faster because of their large size. As long as breeders can ensure sufficient space and food, stable environment and clean and refreshing water quality, they can grow 10-15 cm a year. If the breeding environment is poor and the food is not enough, they can only grow 5-10 cm a year, and some will be even less.

As time goes by, their body size will become bigger. When they mature, the annual growth rate will slow down, only a few centimeters long, and even stop growing properly.

How much yellow-headed side-necked turtles can grow in a year has a great relationship with the way they are raised. If they want to grow fast, they must be given a suitable living environment. Although they can grow rapidly, it is best for breeders not to let them grow very fast, because growing too fast has a great impact on their health.

The maximum length of yellow-headed side-necked turtles can be about 60-70 cm, and their body size is relatively large among turtles. However, artificially raised turtles can only grow to 40-60 cm, and some female yellow-headed side-necked turtles with good physique can reach 60 cm in length. However, male yellow-headed side-necked turtles raised in captivity are generally less than 60 cm long.

If you want to make the yellow-headed side-necked turtles bigger, you should prepare enough space for them to move, and prepare enough food and nutrition to avoid getting sick as much as possible, so that they can develop better.
