Nancy and Mike both made some important points that I wanted to comment on .
when choosing tosai, keep in mind that if they are already at their peak "quality wise" then where else do they have to go (besides down) .......the tosai that make it at the end are truely and ugly duckling story that eventually becomes a beautiful adult ......
because this koi is doutsu, the color so close to the surface of the skin that it appears to be something special. I would be willing to bet this is a male koi that also can finish early.
even if you were able to hang on to what you see right now, as the body of the koi grows the pattern becomes even more "underwhelming".
before I say anything else, I want to commend the poster for being focused
on quality and not overly smitten with pattern. This is an important part of the learning process for folks who intend to show fish with facilities to grow fish to and enter fish over 24 inches. As I pointed out this pattern will not "stay" with the fish as it grows. the trick is to find a big heavy pattern that looks ugly on a little fish that as the fish grows it becomes impressive and powerful. Thanks for posting and pushing forward to learn.
