It is most suitable to breed one hexagonal arowana because they are born with the habit of fighting and competing for territory. If the breeding space or food is not sufficient, it is easy for them to fight. Moreover, the horns of the Hexagonal Arowana are relatively fragile and can easily be injured during a fight. Therefore, when raising them in captivity, it is best to raise them individually.

Tip:

If the breeder can ensure enough space and food, he can also breed multiple hexagonal arowanas of similar size.
