How to choose koi fish?

First of all, I would like to remind novices to understand the classification of koi fish varieties and how to appreciate koi fish before buying koi fish. There are several ways:

1, body shape requires koi fish to have a straight back, a balanced fish, a stable and correct swimming posture and a strong body. The shape of the cheek and the position of the mouth should be correct, without skew, full at both ends without depression, symmetrical and complete fins, and flexible when swimming. Color is the most intuitive embodiment of koi fish, with bright colors, bright colors, clear stripes, neat edges and dazzling colors as the top grade. As for stripes, you can choose according to your personal preference.

2. When choosing red and white, choose the one with big stripes on the head first. First of all, you should see the edge of the red spot on the small fish head, revealing a white mouth, or there are broken markings behind the mouth, which should be very clear. If you can see that erythema, it will be futuristic. Don't cover your eyes with erythema, you should see your eyes, just like the erythema on your head.

3. For the identification and selection of koi fish, it is very important to select its quality first. Koi fish's rhodopsin is pink, which is its own rhodopsin and naturally turns red without coloring. Koi fish, which has a good red color, will naturally turn red even if it is not fed with colored feed after a period of cultivation. This kind of red looks good, strong and good.

Extended data:

Koi fish has a strong physique, bright colors, changeable patterns and beautiful swimming posture, which is of great ornamental and breeding value. Its body length can reach 1- 1.5 meters. Koi fish is distinguished by different colors, patterns and fish scales. Among them, koi fish, a butterfly, was successfully bred in 1980s and is famous for its long and smooth fins. It is actually a hybrid of koi fish and Asian carp, not a real koi fish.
