1, reason: There is white spot on goldfish body to be because water temperature change is too big likely, because temperature difference is too big can stimulate them, make their body produces stress reaction, white spot is a kind of stress reaction.
2. Treatment: The breeder needs to keep the water temperature at 23 ℃ and ensure that the temperature difference does not exceed 2 ℃. When changing water at ordinary times, we should also pay attention to the temperature difference between new water and old water. In autumn and winter, when the temperature difference between morning and evening is large, we can turn on the heating rod to keep warm.
1. Cause: The main reason why goldfish suffer from white spot disease is that the water temperature is too low, because only when the water temperature is below 20 C, the Ichthyophthirius can survive and reproduce in large numbers. Ichthyophthirius usually parasitizes the gills and caudal fins of goldfish. The more obvious symptom is that the body is covered with small white spots. When the condition is serious, the small white spots will become large white spots, and then fester.
2. Treatment: First of all, the water temperature should be slowly raised to above 26 ℃, because the Ichthyophthirius is afraid of high temperature, so raising the water temperature can kill most of the Ichthyophthirius. Secondly, water should be changed in time to ensure clean water quality. Finally, red pump solution, potassium permanganate solution or malachite green solution should be used for medicated bath, once a day, 2-30 minutes each time, and it can be cured in about a week.
