What are koi?
Koi are ornamental carp kept for color, body quality, pattern, and presence. In Japanese contexts, high-quality koi are often discussed as Nishikigoi, with major varieties such as Kohaku, Taisho Sanke, Showa Sanshoku, Utsurimono, Asagi, Ogon, and many others.
What beginners should learn first
Learn water quality before buying many fish. Koi are large, active, waste-producing fish. A healthy pond or tank depends on filtration, oxygen, stable temperature, and enough water volume.
