1. Environmental changes outside the fish tank: The arowana is more sensitive to the surrounding environment, and it is very easy to lie in the tank because of environmental changes. The first is a change in the environment outside the tank. If there is too much noise and strong light, etc., will lead to the arowana frightened, resulting in the situation of lying in the tank.
2. Environmental changes inside the fish tank: In addition to changes in the environment outside the fish tank, changes in the environment inside the fish tank will also cause arowana to lie in the tank. Specifically, there are many situations, such as adding new small fish to the tank, causing subtle changes in water flow and so on.
3, arowana disease: Another important reason is the arowana disease. When they are sick, a very important precursor is to lie in the tank. After the phenomenon of lying in the cylinder, we should consider whether this is the reason and not delay the treatment.
4. Changes in the water environment: The arowana is very sensitive to the water environment. Rapid changes in the water environment can easily cause it to lie in the tank. Specifically, the water environment can change a lot of aspects, such as changing too much water, resulting in large changes in water temperature and PH value, will lead to arowana lying in the tank.
Most of the above four reasons are caused by sudden changes in the surrounding environment, so when farming arowana, we need to pay attention to ensure that the surrounding environment is in a stable state, not dramatic changes. Another special situation is that it is sick, at this time need to timely determine what disease arowana, and then take timely treatment measures.
