The sex of the Chinese tortoise can be distinguished according to their size and the differences in their tails. Normally, the female tortoise is larger than the male tortoise, the female tortoise can reach 4.5 kilograms in adult weight, and the male tortoise can grow to about 1 kilogram in adult weight.
Their tails are also different. The female's tail is short and thin, while the male's tail is long and thick. The distance from the anus to the rear edge of the plastron is also different, the distance from the anus of female turtles to the rear edge of the plastron is closer, while that of male turtles is farther.
Chinese tortoises of different sexes can be kept together. Because Chinese turtles like to live in groups, turtles of different sexes can also live together. But when mixed breeding, we should pay attention to the proportion of male and female. It is recommended to mix two female turtles with one male turtle, or three female turtles with one male turtle. It is usually best to keep 2-3 turtles together. When raising male and female turtles together, we should pay attention to their size difference can not be too large, not more than twice.
