1, look at the size: Ranchu distinguish between the male and female can start from their size. Generally speaking, the male fish looks longer, while the female fish looks shorter.
2. Activity: It can be judged by their activity. In general, the activity of male fish will be relatively high, when grabbing food will be more active, usually swimming speed is relatively fast. But the activity of the female fish will be lower, usually more quiet. If it is during the breeding season, the male fish will prefer to chase the female fish all the time, which is easier to distinguish.
3. Look at the appearance: You can also judge by some characteristics of their appearance. First of all, their reproductive pores, the shape of the female reproductive pores is relatively round, and the male reproductive pores are pointed. Another is their abdomen, which can be observed when they are in the breeding season, when the abdomen of the female fish is relatively swollen, especially when they are about to give birth, while the abdomen of the male fish is relatively flat. And their tails, the male's tail is very strong, and wide and flat, but the female's tail will be smaller.
4. Look at the color: You can also judge by their color. Like many other kinds of goldfish, if the male of the blue longevity goldfish, then their color will be more beautiful, the female of the color will be darker, easier to judge.
Ranchu goldfish male and female can be raised together. Ranchu goldfish's temperament is relatively mild, generally will not fight with each other. Moreover, regardless of male and female, habits and characteristics are basically the same, it is easier to adjust the surrounding environment. However, if mixed farming, we need to pay attention to providing enough food, otherwise the male fish may get relatively more food.
