Koi size
If you want to level up the koi care, it’s a good practice to measure them every month to ensure proper growth. It’s important to measure them properly as not to stress them.
If you want a good mix of colors, I recommend kohaku, sanke, utsuri, platinum, and soragoi. This provides a balance in both their personalities and color combinations.
A garden with a koi pond is a sight to behold. The long lifespan of koi ensures our enjoyment with them for a long time. My office staff loves feeding them. Koi fishes are a complete package in terms of color, personality, size, and the ease of keeping them. They are in a league of their own.
