A Kohaku is a white fish with red (hi) markings. The Kohaku is the most popular variety and it is said that the hobby “begins and ends with the Kohaku.” In evaluating Kohaku, the brightness of the color and the crispness of the edges (kiwa) are judged, along with the soft white of the background. Because the Kohaku has what may be called a “simple” pattern, judging in competition is very stringent and factors such as the balance and complexity of the pattern is weighed against an ideal. As the fish increases in size, it is said that the pattern becomes less important than conformation and skin quality. A pattern that is suitable for a small fish may not look as good on a jumbo.
