1. Reasons for the dragon fish lying in the tank
1. The water quality fluctuates greatly : A large number of water changes, a large number of replacement and cleaning of filter materials and other operations can easily lead to large fluctuations in water quality, especially after changing the water for the old tank, it is more likely to cause large fluctuations in water quality. The phenomenon of lying in the tank when many arowanas are initially put into the tank is generally caused by not adapting to the water quality.
2. The internal and external environment of the fish tank
has undergone major changes: Arowana is very sensitive to changes in its surrounding environment. The environmental changes in the tank include changes in the number of polycultured fish and changes in equipment in the tank. Changes in the speed of water flow, changes in light intensity, etc., these slight changes may cause the arowana to be nervous, resulting in the phenomenon of lying in the tank. In addition, changes in the surrounding environment outside the tank also cause the dragon fish to be frightened and lie down in the tank, such as changes in the background.
3. Arowana disease: Arowana will also have the phenomenon of lying in the tank when it suffers from certain diseases, and the phenomenon of the arowana lying in the tank caused by this reason is the same as the above two situations. There is a difference. The owner can carefully check the body surface and appetite of the dragon fish to judge whether the dragon fish is sick. If the dragon fish often lie in the tank during the day, but it is normal at night, this situation is mostly caused by the mental problems of the dragon fish.
4. Arowana’s mental stress: Arowana’s mental stress is closely related to environmental changes, but there are certain differences. In addition to some changes in the environment, if there are natural enemies of the dragon fish in the environment, it will also cause the spirit of the dragon fish to be on alert. In addition, the sudden appearance of abnormal sound and light signals around the breeding environment may also cause the arowana to be frightened and lie in the tank.
Second, how to deal with Arowana lying in the tank
1. Try to keep To keep the water quality stable, avoid large-scale water changes, change a quarter of the water each time, and maintain regular water changes; for some aging filter materials, avoid large-scale cleaning. It should be cleaned or replaced in batches to avoid damage to the nitrification system, resulting in large fluctuations in water quality.
2. Try to keep the breeding environment relatively stable. Once the dragon fish is in the tank, don’t change the equipment and decorations in the tank casually. In addition, you should also pay attention to avoid changes in the surrounding environment outside the tank, and avoid abnormal sounds and sudden light around the aquarium. The stability of the environment is conducive to arowana emotional stability and good appetite.
3. If the arowana appears to be lying in the tank due to illness, the owner needs to give symptomatic treatment to the arowana. After the arowana recovers, the phenomenon of lying in the tank will disappear.
This is the end of our analysis of the reasons for the arowana lying in the tank. Generally speaking, in order to avoid the phenomenon of the arowana lying in the tank, we must pay attention to it. Keep its feeding environment stable.
