How to divide arowana into male and female? Which is healthier?

Arowana can be distinguished from females in terms of body shape, head, ventral fins, abdomen and cheeks. Most male arowana are much bigger than female arowana, and their heads are bigger than female arowana. The ventral fin of male arowana is very sharp, and the marks on his cheeks are irregular, while the abdomen of female arowana is more prominent than that of male arowana. In addition, we should pay more attention to their eyes, mouth and body when selecting arowana, so as to select arowana with better quality. First, how arowana divides male and female is very simple. Just look at their body shape, head, ventral fins, cheeks, abdomen and other places. Arowana, like most fish, is mostly male fish, much larger than female fish, and the body of male arowana is longer than that of female fish. Arowana is a little different from other fish. Male fish need eggs, so it can be seen that the head of male fish is much bigger than that of female fish.

Anyone who has raised arowana should have seen type A marks on their cheeks, and the marks of male arowana are irregular. In addition, the most obvious place for male and female arowana should be the abdomen. Generally, the abdomen of female arowana will be more swollen than that of male fish. This is because the female arowana needs to ovulate when it matures, so its abdomen is more swollen than that of the male.

Second, what kind of arowana is healthier? Look at arowana mainly by their eyes, mouths and bodies. The health of these three places must be good quality arowana. Healthy arowana generally has flat eyes, and those who fall out of their eyes are inferior. The mouth of arowana should not be higher than the upper jaw, otherwise the appearance of the soil will affect the appearance. The body of arowana must be straight. Nowadays, many arowana are V-shaped because they have been in a narrow space for a long time, which also affects the viewing.
