New pond, 7200 gallons.
pH : 8.2
Ammonia : 0
Nitrites : 0
Nitrates : 0
kH: 120

This is the only fish in the pond, been there about two weeks. Pond bead filter has been running for three months. Sieve and shower went online a handful of days ago.

This fish has been like this for several days now. I’ve been doing consistent water changes daily to the tune of 10%. I use ST religiously when doing changes. It doesn’t seem to be getting better or worse. It’s a liner pond with nothing to rub against. No possibility it’s sun burn.

I can pull him out to a QT if need be, but I thought I’d post a lower quality picture here to get opinions first.

From the quality of the picture I can't be sure but I think it is just a color issue. Yellow koi get their color from the same type of chromataphor as red koi and the color of weaker genetics will change from red to orange or yellow to orange and in some cases from yellow to red or vice versa. I really think it is just genetics.

Thanks, this is a Kage Hi Utsuri ... so it’s supposed to be a deeper orange ...

I would say net it and try to get some better pics. From this photo it could be color change, it could be a bad infection. Unfortunately the water movement, clarity, etc within the photo hinders people chiming in.
