The fish tail has the blood silk generally not to use the medicine. There are many reasons for this, but it is basically a matter of water quality, so as long as the water quality is maintained and the fish can recover by themselves for a period of time. If you have to use drugs, usually choose terramycin mixed with food, as long as three days can be recovered.
1. Poor water quality: Poor water quality is the main reason for the bloodshot fish tail. This may be a problem with the water source itself, or it may be caused by the lack of water exchange, if you want to solve it, in addition to choosing a reliable water source, you should also pay attention to the frequency of water exchange, once or twice a week.
2. Bacterial infection: If there are some harmful bacteria in the water, they will invade through the wound on the fish's tail, which will also cause blood streaks on its tail. If you want to solve the problem, you need to put some bactericidal drugs into the fish tank, such as potassium permanganate, and so on, you must control the concentration, so as not to cause harm to the fish.
3. Parasitic disease: Parasites infect the tail, which can also cause blood streaks on the tail of fish. This requires the use of insecticides to eliminate it, as long as the parasites are eliminated, the disease will gradually recover.
4. Too low temperature: If the temperature is relatively low, some fish that are not tolerant to low temperature will have a stress reaction, so that there will be blood streaks on the tail. At this time to do the appropriate temperature, but not too high, the sudden change of temperature on the fish have a stimulating effect, can be stable slowly warming.
