. 1. Reason: If the water is not changed for a long time, the excrement and food residue of the arowana will ferment and pollute the water quality. If arowana grows in this environment for a long time, it will lose phosphorus.
2. Treatment: In this case, you need to clean the fish tank first and then change the water. You can't change all the water every time you change the water. You can change one third of the water every time. You need to change the water for a week.
1. Reason: The arowana is easily disturbed by the outside world. If there is a sudden abnormal noise in the breeding environment or a threat to the arowana, such as a big cat or a large dog, the arowana will be disturbed and the tank will be hit.
2. Treatment method: At this time, we should try our best to ensure that the maintenance environment is quiet and stable, except for feeding and changing water, do not disturb the arowana. In two to three days, the situation of the arowana hitting the tank will be alleviated, and there will be no loss of phosphorus.
1. Reason: In the process of fishing, if sharp physics is used, it is easy to damage the arowana and cause phosphorus loss.
2. Treatment method: Add salt to the water to sterilize. Keeping the water clean is also good for the recovery of arowana. Or raise the water temperature to about 32 degrees, which can also speed up the recovery of arowana.
