To sum up, 10 species of fish are not a good polyculture. Because they have a strong sense of territory, temperament is irritable, easy to attack fish close to their territory, bite them with their mouths. This is also the reason why it is called "cheap mouth" by fish friends. Therefore, this kind of fish is more suitable for monoculture or breeding with the same kind of fish, not with other species of fish.
Although ten fish are not suitable for mixed culture, it does not mean that they cannot be mixed with other fish. In fact, when it is actually farmed, it can be farmed with some fish larger than it. Specifically, red arowana, silver arowana, lucky fish, golden arowana and other fish with a body length of more than 30 cm can be raised with it. Large arowana can suppress ten fish, so that it does not dare to make trouble and fight.
Ten fish cannot be mixed with map fish. Because the ten fish are very fierce, the map fish may be attacked if they are mixed. If the size of the map fish is similar to or smaller than the size of the ten fish, then they are likely to be bitten or killed. Map fish may fight even if they are larger than ten fish. So these two kinds of fish are not suitable to be raised together.
