This time, I summarized the state of Nishiki-koi growing in the pond made in 2017. Nishiki-koi, which was around 10 cm, has grown into a splendid figure after 5 years. It's getting warmer and warmer, so I took it out as a pond maintenance! When you see it up close, you will be surprised at its size. If you are thinking of buying and growing Nishikigoi from now on, I hope it will be helpful for you to grow up to this level in a few years!
