Why is the arowana lying at the bottom of the tank? What should I do?

Poor water quality: The arowana may be lying in the tank because the water quality is getting worse. There are a lot of bacteria in the water, which constantly erode the arowana, causing them to feel ill and lie at the bottom of the tank. At this time, the old water should be replaced immediately and the new water should be replaced. Sick: It may also be because the arowana is sick. At this time, the water should be changed immediately, and then treated by warming up, adding salt, and taking medicine. Hypoxia: It may also be due to lack of oxygen in the arowana. If the arowana has difficulty breathing, it will lie at the bottom of the tank. At this time, oxygen should be given immediately.

1. Poor

water quality 1. Reason: If the water body is neglected and the water is not changed frequently, the water body is easy to breed bacteria. Bacteria will continue to erode the arowana, arowana, resulting in their physical deterioration, loss of energy, resulting in the problem of lying in the tank.

2. Treatment method: Change the new water immediately. After changing the new water, it is better to raise the water temperature by 2 ℃, so as to disinfect the water body.

Two, sick

1, reason: When the arowana is sick, there will be the phenomenon of lying in the tank, such as white spot disease, anorexia and other diseases, which will make the arowana feel tired, leading to climbing the tank.

2. Treatment: Change the water immediately, raise the water temperature, and add salt at the same time, which can effectively kill the bacteria in the water. After determining the symptoms of arowana, medication should be used in time, such as white spot disease, spraying 0.1 ~ 0.2 ppm mercurous nitrate in the whole tank, which can kill the fallen Ichthyophthirius. If it is anorexia, it can be treated with digestive drugs.

3. Hypoxia

1. Reason: If the water is not changed at ordinary times and the density of feeding arowana is relatively high, the dissolved oxygen in the water will be relatively low, resulting in poor breathing of arowana and the problem of lying in the tank.

2. Treatment: Change the new water immediately. The new water should be exposed to the sun for three days, which can play the role of disinfection and oxygenation. Moreover, it is necessary to explode oxygen in time to increase the dissolved oxygen in water so as to facilitate the breathing of arowana.
