When farming the silver arowana, a very important point is the water quality problem. Fish can only grow healthily in fresh water. As long as the water quality can be guaranteed to be fresh, the water should not be changed too frequently in peacetime, usually once every 3 to 5 days. In the cold season, the frequency of water exchange should be reduced, and it is recommended to change water every half month. When changing the water, you only need to pour out a quarter of the old water and add new water, which can ensure that the water temperature will not change too much.
The water used for raising fish should be determined according to the living environment of the fish. Silver arowana prefer to live in weak acid water with low hardness and clear water quality. Therefore, it is better to use weak acidic soft water as its growth water environment. Under domesticated conditions, it may not be possible to provide the fish with its favorite environment. However, some methods can be used to meet its water quality requirements. If tap water is used as its water, dechlorination should be carried out before use. The effect of chlorine removal can be achieved by drying water in the sun. Fish like to live in soft water with low hardness, but the water quality of tap water is hard, which is not conducive to the survival of fish. In order to reduce the hardness of water, you can pour one third of the boiled water to soften tap water, try to ensure that the hardness of water is between 3 and 12. In addition, it is necessary to ensure that the water quality is weakly acidic, and the PH can be adjusted by adding appropriate salt to the water. In this way, improved tap water can be used to breed silver arowana.
