1. Look at the carapace: Stone golden turtle can judge male and female by the shape of carapace. The carapace of male turtle is relatively long, narrow and looks like a rectangle. The female turtle's carapace is short, but wide, and looks like a circle.

2. Look at the body shape: The male and female bodies of stone golden turtles are different when they are adults. If they are raised in the same environment, the female turtles will be larger and the male turtles will be smaller.

3. Look at the belly armor: The belly armor of male and female turtles is also different. The belly armor of female turtles is relatively flat, while that of male turtles is sunken. Because when the turtle breeds, the male turtle will climb on the back of the female turtle, and the groove of the belly armor can make the male turtle better lie prone on the back of the female turtle.

4. Look at the tail: The tails of male and female turtles are different, and the tails of male turtles are thicker and longer. The mother turtle's tail is thin and short.

The male and female turtles can be raised together, because their habits and environmental requirements are relatively consistent, and they are mixed together. When they reach the breeding age, they are easier to pair. However, in polyculture, breeders should first pay attention to sufficient breeding space, so as to avoid their fighting. Also pay attention to adequate food, so that they can develop better.
