1. The temperature difference is too large: Arowana erect scale disease may be caused by too large temperature difference, and Arowana is sensitive to the change of water temperature. If the temperature difference is too large when changing water, it will cause erect scale disease. In addition, there is a big temperature difference between morning and evening in spring and autumn. If Arowana is in a sunny place, when the temperature suddenly rises or falls, the water temperature in the fish tank will fluctuate greatly.

2, poor water quality: The water quality of Arowana may also be too poor. If the water quality of Arowana is too poor, its resistance and immunity will decrease, and it is easy to induce Arowana at this time.

3. Bacterial infection: Arowana standing scale disease may also be bacterial infection, for example, they are not treated in time after trauma, or gastrointestinal injury will cause bacterial infection.

There is no fixed time for Arowana erect scale disease to be cured, because different causes and treatment methods have different recovery times. If the water temperature is too low or the environment fluctuates too much, as long as the breeder heats up and explodes oxygen in time, they can generally recover in a few hours.

If it is caused by bacterial infection, it will take about 3-4 days. However, the specific cure time depends on the severity of the disease. If it is serious, it may take about a week.
