It is better to mix seven-star saury with silver arowana, map fish and other larger fish. When mixing, be sure to pay attention to the stocking density. Although the seven-star saury are relatively mild-mannered, if the tank is too small or the stocking density is high, they will also fight for territory.

Do not choose smaller fish, otherwise you must avoid The big fish eats the small fish, which leads to fewer and fewer saury in the tank.
