My plecos look like they have open wounds on them or some kind of fungus. They are pink blotches that look like open sores. Water quality is good. Is there anyway to treat this?
1. I change 80% of the water every 3 day
2. I have had the fish 6 weeks and I remember a few having little wounds near there head. I just figured they were battle scars.
3. Of the 12 that I have maybe 5 have it
4. No new fish or plants
5. They are all by them selves but could be injuries from each other and they are not healing and spreading

I added Melafix yesterday.
Any help would be appreciated
