White spot disease is a common fish disease caused by Ichthyophthirius. White spots on the body surface of goldfish can also rot fins. This disease is highly infectious and requires timely water change after discovery. In addition, the water temperature should be raised to 30 C. High water temperature can inhibit the survival of Ichthyophthirius. Drug adjuvant therapy can be used to soak the diseased fish in 0.5% non-iodized salt solution or 2 ppm methyl blue solution (about 6 hours a day). After the white spots disappear, it still takes several days to completely kill Ichthyophthirius.
can be caused by poor water quality or trauma caused by fighting between goldfish. The symptoms are usually white fins, mucus and blood spots in the wound. In this case, the water should be changed first, the water quality should be improved, the water temperature should be raised to 30 C, and the goldfish should be soaked in 0.5% non-iodized salt solution. If the drug is not effective, it can be used according to the proportion of 5 tablets of oxytetracycline in 100 KG water.
Saprolegniasis is also called white disease, which may be caused by goldfish trauma, poor water quality and excessive water temperature difference when changing water. The symptoms are fin ulceration and white hair covering the whole body in severe cases. Saprolegniasis is relatively difficult to treat, and it is necessary to change the water first and raise the water temperature to 30 C after discovery. Oxytetracycline can still be used by adding 5 tablets of oxytetracycline in 100 KG of water. Sick fish also need to use cotton swabs to help them remove white hair, and use ultraviolet lamps to kill mold in the water for several hours a day.
