of feeding 1. Reason: The nutritional content of the food fed at ordinary times is too high, which will make the fish grow very fast. In this way, the capillaries on their body surface will be burst, leading to bleeding. In addition, if the feed to the fish contains additives and growth-promoting agents, it will also damage the skin of the fish, causing the scales to bleed.
2. Treatment method: replace the big fish tank in time and reduce the feeding amount of nutritious food. Feeding nutrition to fish must follow the principle of moderation, and must select high-quality feed to feed fish.
1. Cause: Excessive addition of disinfectant, excessive spraying of fish medicine, excessive chlorine or ammonia in water, etc., may cause fish poisoning, resulting in bleeding scales.
2. Treatment: Use the antidote immediately to reduce the concentration of disinfectant and fish medicine. Chlorine in the water should be removed by heating, and ammonia toxicity and medicinal properties in the water should be reduced by changing the water. Usually, the amount of medication must be well controlled, and fish medicine should be used strictly in accordance with the instructions and the standards of pharmacies.
1. Reason: The deterioration of water quality or the high water temperature will cause a large number of bacteria such as Monas and Streptococcus in the water body to breed and multiply. In this way, fish are easily infected by bacteria. In this case, not only the scales will bleed, but also the gills and eyeballs will bleed.
2. Treatment: If the condition is not serious, salt can be used for sterilization and disinfection. If the situation is serious, you can choose the corresponding drug bath treatment according to the bacteria that breed.
