Take one of your fish to a local Koi store to have them check for you.

Did you check your water parameters? It may not be parasites? I was told
Koi will also jump and flash when the water parameters are off.

Easier and cheaper to do water change and deal with water quality problems
than with ick, fluke, etc.

I know this is a sign of parasites. How do you treat? I read sites
that tell you you need ot do a gill scrape, look at it under a
microscope to determine the type, etc before treating. Let's get real,
I don't have a microscope and can't visibly see anything on the fish.
What should I do?
