My largest silver dollar developed a very sudden outbreak of some sort of fungus on one side of his body. It was the night before last that I first noticed the problem. It was, at first, a sort of lightening of patches on the one side. When I looked at it from different angles, it looked like the patch had been sort of rubbed away. By yesterday, the patches looked elevated and cottony. I'm treating the tank and he seems to be responding well; the patches are all noticably smaller today. He appears otherwise healthy. His gills and fins are all fine; his eyes are clear, he is swimming and eating. All the other fish in this tank are healthy. Any ideas about something to which silver dollars are particularly prone? Any special advice?
