1. Cause: The main cause of arrowworm disease is environmental discomfort or unclean water. Koi fish that have just been transferred from wild fish ponds to artificial fish ponds or tanks are more likely to suffer from this disease. The symptoms of sick fish are manic restlessness, crazy swimming in the water, rolling back and forth, and rubbing against the tank. There will be filamentous parasitism on the back or under the fins of the diseased fish, as well as in the mouth and gills in severe cases.
2, remedial method: Can have medicated bath with dipterex first, general medicated bath 20 minutes can. Then 1 to 2g of dimieling is scattered into the fish tank once a day for 7 to 10 days. Note that in the first three days, Trichlorfon and Trichlorfon can be used at the same time, the effect will be very significant. After 3 days, you can choose one of the drugs to continue to use until the koi recovers.
1. Reason: When the season changes, too much water or too large temperature difference will lead to stress reaction of Koi, such as rolling in the water, hiding at the bottom of the tank, and running back and forth. This usually happens after autumn when the weather is cooler.
2. Treatment: If the koi fish rolls back and forth in the water without hurting itself, it does not need to be treated with medicine. Just keep the water temperature at 25 degrees, keep the water clean, put some coarse salt in the tank, and finally wait for the koi to recover by itself. When winter comes, breeders should take precautions in advance to avoid the recurrence of this situation. If the condition is serious or infected by bacteria, it can be treated with corresponding fish medicine.
