I found 2 nos unknown "white spot" on my ranchu
goldfish's back tail since 1 week ago. Initially I thought it is white spot, where I treated it with copper safe medicine. The medicine didn't work to remove it. After few days of treatment, I decide to put it back to aquarium. The condition of the "white spot" is maintained without getting worse. No symptom of infection to other fish too. Therefore, I have search more information on web and I am wondering whether it is fungus. It is better to ask expert first before I proceed. The picture of ranchu is attached below with red color remark on the "white spot".
