The maximum length of spotted pond turtles can reach 20 cm, but most common spotted pond turtles are between 15 and 20 cm. There is not much difference in size between wild and farmed spotted pond turtles, unless some of them are in good health and can grow to 20 cm, but they will not exceed 20 cm.

The environment in which spotted pond turtles are raised will greatly affect their body size. If spotted pond turtles of the same age live in comfortable environment, their body size will be larger than that in harsh environment. And their physique will be very different. If breeders want to make their bodies develop better, they should ensure adequate environment and food in the process of breeding.

The life span of spotted pond turtles is relatively short compared with other turtles. Generally, their life span is 20-30 years, and few of them will exceed 30 years. How long they can live depends on the breeding environment. Because the young spotted pond turtles have poor resistance and immunity, if the breeders do not take good care of them, they will get sick, which will affect their life span. If the spotted pond turtles are kept in a comfortable environment, have plenty of food and have few diseases, their life span may be prolonged.
