1. The water temperature is low 1. Reason: The reason why the arowana does not eat after changing water may be that the temperature of the new water is too low, and the water temperature is too low, which will affect the appetite of the arowana, so they will not eat after changing water.
2. Solution: The breeder can use a heating rod to slowly raise the water temperature to 24-26 ℃, and then try to feed the arowana after it adapts to the water temperature. When feeding, you can lure them with their favorite food at ordinary times, which can improve their chances of opening their mouths.
2. The amount of water changed is large1. Reason: It is also possible that arowana does not eat after changing water because the amount of water changed is too large, and arowana is sensitive to environmental changes. If the water quality fluctuates too much, it will make them uncomfortable and affect their appetite.
2. Solution: Breeders can keep the surrounding environment stable first, and then adjust the water quality to the state before changing water as much as possible, or control the PH value between 6.5 and 7.5. After a while, the arowana can recover and the breeder can try to feed.
3. Scared1. Reason: Arowana does not eat after changing water. It may also be because it is frightened in the process of changing water. For example, when pouring water, the speed is too fast, and the water flow hits the fish body, which will also make them uncomfortable or frightened.
2. Solution: Breeders should keep the surrounding environment quiet first, and ensure that the water temperature and water quality in the fish tank are stable, waiting for them to recover by themselves. During the recovery period, the breeder cannot feed the arowana.
