1, reason: Do not change water to fish crock for a long time, can bring about the water quality in fish crock to become poor, content of the oxygen in water can be reduced at this moment, make guppy feels unwell, thereby the body can grow white hair.
2. Treatment method: Pour out the water in the fish tank and mix salt water and baking soda to sterilize the fish tank. Then a quarter of the water in the fish tank is replaced and an oxygen pump is used to pump oxygen into the fish tank to provide them with a suitable living environment.
1. Cause: Too much change in temperature or inappropriate acidity and alkalinity in water will reduce the resistance of guppies. At this time, when they are weak, they are easily infected by bacteria and grow white hair.
2. Treatment method: First, fish out the guppies to prevent the spread of germs on them and infect other healthy fish. And then soak that diseased fish in potassium permanganate for 20 to 30 minute each time. Then check the quality of raw water, if it is caused by temperature, adjust the water temperature to 28-30 ℃. If it is caused by acidity and alkalinity, adjust the acidity and alkalinity to 6.5-7.5.
1. Cause: In the process of fishing guppies, if the operation is not appropriate, it is easy to injure them. At this time, mold spores will enter their wounds, causing them to grow white hairs on their body surface.
2. Treatment method: fish out the guppies and slowly raise the temperature around them to reduce the activity of the mold. They are then soaked with methylene blue solution or malachite green solution for 20-30 minutes at a time. Finally, smear their wounds with yellow powder.
