When the Lei Arowana is in the juvenile stage, the distinguishing characteristics of the male and female are not obvious, and it is not easy to distinguish the male from the female. After they reach adulthood, that is, the age of sexual maturity, it is easier to distinguish between male and female. Specifically, it can be distinguished from the following aspects:
1. Body shape: First, you can see their body shape. After maturity, if the female fish looks shorter, the male fish will be slightly longer.
2. Appearance: You can also observe their appearance. There are many differences in appearance. For example, the dorsal fin and caudal fin, the smaller is the female fish, the larger is the male fish. And their breasts, the breasts of females are more rounded than the breasts of males, and they are softer to the touch, especially during the breeding season. You can also see their gonopores. The female fish's genital pore is relatively large, and prominent, the shape is triangular, the color is pink; The reproductive pores of male fish are not obvious, slightly pink and pale in color.
3. Color: It can also be distinguished from their color characteristics. There are some regular and small spots on the dorsal fin of female fish. The male fish are large and irregularly arranged, although they also have white spots.
The male and female brontosaurus can be raised together. Although their character is more fierce, but mixed breeding between male and female will not increase the probability of fighting. Because even if the male and female are raised separately, they will still be more aggressive and easy to fight. In the process of breeding, in order to avoid fighting, an important task is to provide them with enough food.
