1. Cause: Long-term non-replacement of water leads to turbidity of water quality, reduction of oxygen content in water and breeding of a large number of bacteria. Fish in this harsh environment for a long time will weaken their resistance. At this time, the pathogen attaches to the body surface of the fish, which can easily make the fragile fish sick.
2. Treatment: There are a lot of bacteria in the fish tank, so the fish tank should be sterilized first. A mixture of salt water and baking soda can be used to sprinkle the tank several times. And then that fish is put into the potassium permanganate solution for medicate bath treatment for 20 to 30 minutes each time. At the end of each bath, rinse the fish with warm water. After washing away the liquid medicine, it will be fed in saline water, and after a period of time, the white hair will decrease.
1. Cause: When transporting or salvaging the fish, the scales of the fish fall off or the fish is scratched due to improper operation. The wound was not treated in time, and mold spores invaded the wound, causing fish to be infected with saprolegniasis. Diseased fish will appear white hair.
2. The treatment method is to isolate the fish and raise the ambient temperature to reduce the activity of the mould. Using methylene blue solution or malachite green solution to immerse and wash the fish body for 10 to 20 minutes. Then he fished out the fish and smeared yellow powder on its wound. Treat it once a day for a period of time, and the symptoms can be alleviated.
