, fish tail has red blood silk to be able to use furacilin to immerse wash cure. Usually there is no need for red blood, this situation is mostly caused by stimulation, medication can not play a very good role, but will be counterproductive. If you want treatment, first of all, you should stabilize the water temperature, keep the temperature constant, and change the water in time to improve the water environment. In addition, you can add salt appropriately, but the concentration should not be too high, usually not more than five thousandths.
1, water quality is too poor: Do not change water for a long time to be able to bring about water quality aggravation, water quality is too poor to be able to stimulate a fish, let fish tail produce red blood silk thereby. This situation requires regular water changes to improve water quality, but also to strengthen filtration, so that the water body gradually gets better, so that the fish will slowly recover.
2. Fluctuation of water temperature: Fish is a poikilothermic animal with weak adaptability to temperature, so once the temperature changes, it will also cause some stimulation to the fish, resulting in red blood on its tail. Therefore, attention should be paid to heat preservation at ordinary times, and the temperature should be kept constant so that the fish can grow healthily.
3. Parasites: If the tail of the fish is infected with parasites, it will also produce red blood. The parasite, called Uterotropis, can be infected by rubbing, so fish should be isolated as soon as possible and treated with insecticides.
