What should be paid attention to when appreciating red and white koi?

When enjoying the red and white koi, you should pay attention to the following:

First, the background color is white and nearly pure white, especially the bright white background is the best. If it is a yellowed white background or black spots, the evaluation is inferior.

Second, the edge of red markings is obvious but not blurred is the best.

Third, the crimson tone is the best.

Fourth, whether it is large or small markings, there must be red markings on the head. However, the "covered" carp whose heads are all red have lower ornamental value.

Fifth, the configuration of scarlet plate or zebra should be symmetrical.

Sixth, the erythema between the head and trunk cadres is better for those who cut in. Red can not reach the mouth, eyes, pectoral fin, dorsal fin and caudal fin and so on.
