The main point of viewing Dazheng Tri-color koi fish is that there are no black spots on the head, but there must be black spots on the shoulders. Black spots on white background are called acupoint ink, and spots on erythema are called overlapping points, among which acupoint ink is the best.
Secondly, the ink dots should not be messy, but must be evenly distributed, balanced left and right, and harmonious before and after.
It should be noted that there should not be too many dark spots in the back half of the body.
So it's good to have black spots on Dazheng tricolor tail. Can you observe its distribution?
