Help diagnose koi with red ring around eye and brown fungus like parches on head
A45D9865-7E1F-4F63-B666-646E2C77689C.jpegI have little experience and recently found that I had a build up of sludge on the bottom of my pond. I had been doing regular water changes and keeping the filter clean. I did get a vacuum and cleaned the bottom.
Shortly after I found a koi covered in light gray fungus.
i just found a yellow koi with brown nostrils. They are Pom poms I think but have changed color and a red ring around the eye. Could this be damage from methane or bacterial infection from the sludge removal?
He is quarantined with salt added.
Im not sure how to treat.
Id appreciate any help,
thanks
