That SD who has that growth thing and the torn fins now has two white spots on his dorsal fin. I just noticed them today. I don't think it's ick because the temp hasn't dropped. Another SD once had something similar that ate a small hole through the fin and then disappeared. Maybe it's just a new marking? Something must be wrong inside him. Constantly he's getting growths or strange marks.

Water parameters as of yesterday's test:
