I. Hypoxia in the water
Arowana The bubbles on the water surface may be caused by the lack of oxygen in the water. When the oxygen content in the fish tank
is insufficient, it will cause the arowana to float its head or spit bubbles in the water. The arowana will also stick its mouth out of the water, just like breathing oxygen in the air.
Solution: At this time, the pet owner needs to replace the water in the tank, because there is sufficient oxygen in the new water, but the amount of water changing each time should not be too much, just change one third of the water. . If conditions permit, an oxygen pump can also be installed to ensure sufficient oxygen in the water where the arowana lives.
Second, water quality and temperature issues
Although Arowana is sensitive to water temperature The water quality requirements are not very high, but if the water quality is too poor, the pH changes, or the water temperature is too low, causing the arowana to feel uncomfortable, which will also cause the goldfish to float on the water and spit bubbles.
Solution: If the problem of water quality and temperature causes the goldfish to spit bubbles on the water surface, the pet owner should adjust the temperature in the fish tank to about 25°C in time (the most suitable temperature for raising arowana), It is also necessary to replace the water quality in time, control the PH value of the water between 6.5-7.0, and keep the water in the fish tank weakly acidic.
Three, Arowana indigestion
It’s like a burp , When the arowana is indigestion, the digestive system of the arowana will produce waste gas. After the waste gas accumulates to a certain extent, it will emerge from the mouth of the arowana to adjust the balance of internal and external air pressure. This condition is usually caused by the arowana eating too much or eating indigestible food.
Solution: In this case, the pet owner can first fast for 3 days for the arowana, and then feed the arowana to eat some digestible food after 3 days, such as aquatic plants, cooked millet Wait. If the arowana still has the behavior of spitting bubbles, it proves that it cannot digest food, and it needs to be fed an appropriate amount of digestive aids to the arowana to adjust.
