Razor turtles can be polybred, as long as they pay attention to the difference in body size when choosing turtles. In addition, as far as possible, don't choose fierce turtles to mix with razor turtles, because razor turtles are more lively, and if the mixed turtles are more intense, fights may occur. Therefore, giant turtles, grass turtles, musk turtles, map turtles, swamp side-necked turtles, etc. can be selected for polyculture. Be careful not to mix razor turtles with small turtles to prevent fighting.

Razor turtle is a kind of deep-water turtle, which needs high water level when breeding. When selecting mixed turtle varieties, we should also pay attention to whether their living habits are similar. When breeding, we should also pay attention to choosing a larger breeding tank, because razor turtles are relatively large in size, and they also like to move around, which requires a large living space, so we should also pay attention to the problem of space when breeding.

Razor turtles can be raised together. However, attention should be paid to selecting turtles with little difference in size. Because these turtles are lively and active, and like to live in a relatively large environment, they should be bred in a relatively large tank as much as possible. Pay attention to the amount of feeding. If the breeding density in the tank is relatively high, ensure that the amount of food is sufficient, otherwise they may fight and cause casualties because of grabbing food.
