The sexes of Chinese flower turtles can be differentiated based on their body size and differences in their tails. Under normal circumstances, the body size of female turtles is larger than that of male turtles. Female turtles can weigh up to 4.5 kilograms in adulthood, and male turtles can grow to about 1 kilogram in adult weight. Their tails are also different. Female turtles have slender tails and male turtles have thick and long tails. The distance from the anus to the rear edge of the plastron is also different. The distance from the anus to the rear edge of the plastron in female turtles is relatively short, while the distance from the anus to the rear edge of the plastron in male turtles is farther.

Chinese flower turtles of different genders can be raised together. Because Chinese turtles like to live in groups, turtles of different genders can also live together. But when mixing, pay attention to the ratio of males and females. It is recommended to mix two female turtles with one male turtle, or three female turtles with one male turtle.
