Cecil, it looks like ammonia toxicity to me. Have yo checked the level lately? Is this the pond that was not taking feed well?
Add a couple hundred ponds of stock salt to the water since that seems to help.
I don't think so Rex. It's only effecting a few of the fish and they weren't accepting feed as well as they used to while I was still running the well. I just don't believe there are enough fish in the pond to get ammonia levels up in 100,000 gallons.
I may crank up the well but that can be as stressor too with a sudden increase in iron and drop in PH.
