On the one fish's pectoral fin, the white blobs are white grubs and the baclk spots are black spot disease. Both are parasites with part of its life cycle spent in snails. Hopefully your RES stocking will help control the issue.
The red colored eyes are nothing to be concerned about. It is a natural variation in genetics seen in BG. I often see CNBG with red eyes, perhaps more so than not.
With a healthy population of LMB and BG, I believe you'll quickly notice far fewer GSF present.
