Cameron Reid –
The Kohaku Koi arrived healthy and vibrant. The white body and bright orange markings are striking. After a few weeks, I noticed the head markings are darker than the body, which matches the description. The fish are active and seem to enjoy their environment. A great addition to any pond setup.

I’ve had several Koi before, but this Kohaku stands out. The kiwa outlines are crisp and well-defined. The fish have grown steadily and show good color development. I’m impressed by the quality and the care taken in breeding.

The fish look beautiful and are in good condition. The coloration is as described, though the body markings are still a bit lighter than expected. I plan to keep them for several years. They seem to be adjusting well to the pond.
