Compared with male fish polyculture, female fish polyculture is relatively easy, which may be related to the aggressive character of male animals. But arowana is hard to distinguish between male and female, so this is not the most important place for arowana polyculture.
For the polyculture of arowana, it is easier to raise it from the young fish, because the young fish are bold and have strong adaptability after entering the tank, and there will be no too fierce fighting when polyculture.
Extended data:
Fish farming needs water first, and strong filtration is a necessity for arowana polyculture. Mixed culture of arowana requires higher filtration than single culture of arowana. With the increase of fish, leftovers and fish droppings will also increase. Only strong filtration can provide a high-quality living environment for arowana and avoid many arowana diseases caused by water quality.
Arowana is very territorial, so you should observe the mixed arowana at any time when entering the tank. Fighting is normal, but if it is too fierce, we need to deal with it. This also requires that the dragon tank must be bigger, which can provide escape space for the inferior arowana.
After fighting with arowana, the scales will fall off, the last three fins will crack, and in severe cases, the beard, tail and even death will be lost. Therefore, when the tail fin of arowana is divided, the betta can be isolated with a glass partition to avoid more arowana diseases caused by mixed culture of betta.
