Hi, has anyone a idea why one of my koi might move it's gills a lot?
Another koi seems to move its mouth a lot.
Have checked the water and everything is spot on.
All koi are eating fine just seem to be a bit eratic at times.
Think it might be some parasites as I've seen one flick as well.

It might be worth having a look at the gills. Gently pull back one of the plates, only as far as you would see them open. The gills should appear uniformly pink in colour.

Ive tried it on my big shiro. To be honest I'm not sure where I'm looking for.
It looked all nice pink and a bit paler on the ends.
I did take a scrape as well, was not that lucky with that one.
I have only a cheap microscope. Tried to find something for ages.
Just when I saw a dead fluke the light packed in on my microscope.
Not sure now if it was a skin or gill fluke.
Thought it was a gill fluke (had some in spring)
Treated already 5 days ago with Fluke M but there seems to be no change in
the koi's behavior. Double checked water, all fine.
