The golden man arowana can grow to about 10-20 centimeters, but it is usually only 7 or 8 centimeters for family farming. How big it can grow is often closely related to its growth environment, water quality and feeding bait. If there is enough space to move around, and the water quality is more suitable, it can grow bigger if it is fed enough bait every day.
The life span of the golden man arowana is about 2 years, not more than 3 years at most. If you want to make it live longer, you need to provide a comfortable growing environment and change water regularly so as not to affect its health after the water quality decreases. In addition, if you feed live bait to the fish, you must do a good job of disinfection, which can also reduce the possibility of its disease.
1. Change the water: When the kingman arowana is sick, the first thing to do is to change the water. The original water often contains high levels of bacteria or parasites. Changing the water can dilute the fish and prevent the disease from getting worse. Usually, water should be changed every day, at least every other day, so as to improve the water quality.
2. Raising the temperature: After changing the water for the Kingman arowana, the next thing to do is to raise the temperature. The water temperature should be controlled at about 29 ℃, which is higher than usual. This can stimulate the fish body, thus stimulating its own immunity and making it better resist diseases. Heating also has drawbacks, accelerating the reproduction of bacteria, so salt should be added appropriately.
3. Adding salt: By adding salt, the osmotic pressure of water can be increased, thereby reducing the invasion of pathogens into the body of the kingman arowana. The concentration of salt should not be too high, not more than five thousandths.
