The water quality is not good: the ammonia nitrogen content in the water is too high, which needs to be improved by changing the water in time, once a week. | | Sudden change of temperature: The change of temperature makes the fish feel uncomfortable. It is necessary to stabilize the water temperature and gradually increase the temperature. | | Injuries from fighting: Injuries from fighting between different fish. In this case, it is best to separate the fighting fish. | | Scratch the fish tank: The fish tank is too small or there are sharp objects in the tank.

1. the water quality is not good
, the fish body bleeds, usually because the water quality is not good, causes it to receive certain stimulation. In this case, the best solution is to change the water. In the daily feeding process, water should be changed, usually once a week, about a quarter of each time. Be careful not to change the water violently, so that the situation will not get worse.
2. the sudden change
of temperature must control the water temperature, even for wide-temperature fish, the temperature can not change too much, otherwise it will lead to body bleeding. It is better to install a heating rod in the fish tank, so that the temperature can be kept constant, so as not to affect the health of the fish. If tropical fish are raised, the water temperature is above 20 C. When
different kinds of fish are mixed together, they will inevitably fight. Once they fight, they will inevitably be injured. The wound will bleed and even be infected by bacteria, which will pose a threat to the survival of the fish. Usually, after finding the fish fighting, they need to be separated at the first time, and the injured fish should be raised separately to avoid secondary injury.
If the fish accidentally scratches the fish tank while swimming, it may also be injured and bleeding. Usually, the tank used for fish farming should not be too small, and there should not be too sharp objects inside, otherwise the fish will be easily injured. It should be noted that when fish feel uncomfortable, they will also rub against the tank, which requires immediate treatment.
