How about Huang Qiucui koi and the color characteristics of Huang Bijia koi?

Huangqiucui koi and Qiucui brocade carp have the following similarities:

In terms of body size, Huang Qiucui koi is the same as Qiucui brocade carp, with a slightly fat abdomen.

In terms of scales: both are also covered with scales on the back, extending from the beginning to the tail handle.

Color: Huang Qiusui koi is also distributed in the face, abdomen and dorsal fin and other directions.

Ki-Shusui, as its name implies, is yellow, but the back is still blue. if there is a koi with black scales on its back, it is called "German yellow pine leaves".

1. Huang Qiucui's head color is not as strict as Qiucui koi, but there can be no impurities, and the yellow part cannot have black spots or other colors, otherwise it will affect the ornamental value.

2. The back color must be blue, otherwise it will be "German yellow pine leaf".

The second is that, like other koi fish, they should have a strong and pure color to see whether they are in good shape, vigorous, trauma, bleeding and other symptoms.

In addition, it is necessary to observe whether the fish has white spots, white villi, blood filaments and ulcers, and then to see whether the chest, abdomen and caudal fins are complete, whether they are happy and lively when swimming, and whether there are rolling, side-lying, handstand or sinking phenomena. You can't choose unhealthy fish.
