The culture of saury needs to be kept in a dark place, and the water temperature should be controlled above 20℃, so as to grow rapidly. Because this kind of fish only eats live bait, it should be fed with small fish and shrimp. Its food intake is large, but it should not be fed too much, otherwise it will pollute the water quality. It is native to South America, and it is aggressive and territorial, so it is difficult to mix with other fish.
