At the initial stage of infection, goldfish behave as usual, but there will be a small number of white spots on the body surface, and sick fish will look for hard objects to rub against the body in order to get rid of parasites.

In the early and middle stage of the disease, we usually raise the temperature in the fish tank and keep it at 28030 ℃ during treatment. After a few days, the parasite cysts on the fish's body surface will automatically fall off. The heating up here should not be too fast, and it is appropriate to rise at a rate of 2 to 3 ℃ per hour. After the cysts fall off, a red mercury solution of 0.05 to 0.07% concentration can be added for follow-up medicine bath to further strengthen the elimination of pathogens. The treatment of diseased fish at this stage can also be sprinkled with 1~5ppm 's furacillin powder. Dip the match stick in methyl blue crystal powder and rinse into the diseased fish box to change color.

Fish are very sensitive to this drug and are easy to cause death. If you want to use it, you should control the amount and do not use it easily.
