all the time? If the breeding density is not high, the arowana does not need to explode oxygen all the time, because the dissolved oxygen in the water in the fish tank is enough for them to absorb. Breeders only need oxygen during the day. And they will rest at night, and their need for oxygen will be reduced. If the feeding density is high, it is necessary to explode oxygen all the time, otherwise the arowana will suffer from hypoxia. After anoxia, arowana will hit or jump into the tank, which is dangerous, and breeders need to pay attention to it. If possible, a lid can be added to the top of the fish tank to avoid this situation.
arowana? It is difficult to raise arowana, because they have higher requirements for water temperature, water quality and space. First of all, the water temperature, they are tropical fish, like the water temperature is between 24-26 degrees Celsius, they are more sensitive to temperature differences, breeders need to use heating rods to ensure that the water temperature is constant. Furthermore, the water quality, they need to use the tap water after exposure to the sun, usually need to control the PH value between 6.5 and 7.5. It is better to change water 1-2 times a week, and the amount of water changed each time should be controlled at one third of the total amount of water. Finally is the space, the arowana's bodily form is big, after the adult body length can achieve 50-120 centimeters, therefore the breeder needs a 120 * 60 * 60 centimeters fish tank at least to raise them.
