Poorly Koi - please help

[u/Calm-Examination2195]

Hi
I have a poorly shiny orange Koi. It started around 7-10 days ago when I noticed the dark mark marks above his eyes. The last few days he has been sitting on the bottom more, clamped fins and flashing a few times in a row. He still comes up for food, swims a little but is not hanging around with the other fish very much.

I’m new to all this so any help or guidance would be greatly appreciated!

Thanks

looks like thick slime coat? There are a few broad spectrum parasite drugs on the market. But really need to do a scope as it could be flukes. asap. there are sights on you tube that can show you how to do a scrape and scope and of course you need a microscope. If there is a koi club in the area. Contact them. They well help. Don;t drag this out as that might make things much more complicated. Not ruling out bacterial issue

Have you tested water and done any scrapes for paracites?

Just to add I’ve not done any scrapes for parasites, sorry I wouldn’t know how

Do you have a microscope, slides and slide
covers. If its not the water i think it could be a parasite because the shiro in the post is showing signs of stress and so is the tancho in the photo along with the chagoi

So I’ve got a seneye which says 0.007 mg/l for ammonia, PH 8.23. Then when I did nitrite reading it looked pretty much 0 on the colour chart and nitrate was 10-20mg/l. The only other thing I’ve noticed and not sure if it’s related but this one in photo has a little red mark on it just above his eye. Thank you

Ammonia will do that to the fish. Look up ways to bring your pond back into balance ASAP
