up and down crazily? The reason why the fish swims up and down crazily is that it is frightened, but there are many reasons for its fright, which may be the fluctuation of water quality, the fish has not yet adapted, or the fear of the original fish in the tank after the new fish enters the tank. Or a loud noise or light. In addition, if the fish suffer from Chinese disease, trichodiniasis and so on, they may also swim up and down crazily.
1, feeding: fish farming should first pay attention to feeding, feeding is not good can easily lead to fish suffering from enteritis, but also pollute the water quality. It is usually fed two to three times a day, and the amount of food should not be too large each time, so as to facilitate its digestion. In addition, if there is residual bait in the tank, it needs to be cleaned up in time.
2. Change the water: In order to keep the water in the fish tank clear, the water should be changed regularly. However, the water should not be changed too frequently. It should be changed once every one to two weeks. About one fifth of the water should be changed each time. At most, it should not exceed one third of the total water volume. Changing too much water will stimulate the fish and may cause their death.
3. Temperature control: If you raise tropical fish, temperature control is also very important. This kind of fish has limited adaptability to temperature. The water temperature must be kept above 20 degrees Celsius. If the temperature is too low, the fish's appetite will decrease and even freeze to death.
