in salt water or methyl blue 1. Reason: The white spots on the body of Manlongyu may be caused by white spot disease. The main reason is that the water temperature is too low, which makes the Ichthyophthirius grow and reproduce in large numbers. In the early stage of the disease, Manlongyu will rub against the tank. When the symptoms are serious, the fish will be emaciated, less active and depressed.
2. Solution: White spot disease is mainly because the water temperature is too low. If you want to treat it, you must first raise the water temperature to above 26 ℃, because Ichthyophthirius is not resistant to high temperature, and warming can reduce the number of bacteria. If the symptoms are not serious, you can use 5% salt water to soak the diseased fish for several days to kill the Ichthyophthirius. If the symptoms are severe, you can use 2 ppm methyl blue to soak for 1 hour a day for several days. During treatment, the white spots will disappear faster, but after the white spots disappear, it will take a period of medication to completely recover.
bath 1. Cause: White spots on Manlongyu may also be caused by Saprolegniasis, which is mainly caused by bacterial infection after trauma. For example, if the fish is injured during transportation or fishing, it is easy to suffer from Saprolegniasis if it is not sterilized and disinfected in time. Saprolegniasis begins with irregular white spots, and later forms white flocs on the infected sites.
2. Solution: If there are few parts of Saprolegniasis, you can use iodophor to clean the affected area first, and then use potassium permanganate solution for medicinal bath. The ratio of potassium permanganate to water is 2mg: 1L. It is best to take a medicated bath once a day for 20-30 minutes each time.
