What metaphor does koi fish look like?

What's koi fish like? There are the following metaphors:

First, koi fish's body color is bright and changeable. Some are red; Some are mainly red with some beautiful white stripes; Some have black and white stripes; There are also two big koi fish, both golden yellow, which look magnificent. Two big golden koi fish always swim majestically in the water, looking relaxed and poised, just like a general patrolling his city leisurely.

Second, I saw carp jumping out of the water one by one, and their slim bodies, like light Yin Yan, danced in the distant waves; On the blue sea, there are 10,000 flowers, one after another, which are magnificent.

3. The eyes of carp keep blinking, just like the twinkling stars in the night sky.

The body of this carp is red, and a big tail like gauze is covered with red patterns. From a distance, it looks like a big red pompon.

This carp has a black back, like armor, a mouth like a dragon and a tail like an oar.

I hope my answer can help you.
