Just went to LFS & bought more salt (haven't added any for a month or
so) but these aren't sores, they're like scratches on his head and
side. I was amazed these appeared the day after I wrote the message
about spawing or attacking.

he's the only one affected, and he's the biggest fish in there. It
doesn't make sense that a fancy smaller than him would cause those
kind of marks. I'm keeping an eye on him just to make sure.

Water parameters are normal for me.

large "sores"? round sores? you got an algae eater in that tank? airstones dont
stress GF. what are your water quality parameters, ammonia, nitrites, nitrates and
pH? change some water, add 1 teaspoon salt per 5 gallons, no additives, dissolve
first, add slowly. treat sores topically, but keep changing water every day.
