I hope someone can help me, I have come back from uni and noticed a couple of the fish in my mums pond did not look right, they are eating and swimming fine but have have clear physical diseases/infections of some sort.
The pond is around 4,750 gallons and is running a PondXpert SpinClean 20000 filter with UV.
I have caught the two fish out that appear to have these issues for photos, in hope that you can identify what is wrong and what treatment is best for the fish and to treat the entire pond. All the other fish appear in very good health.
