Choosing Your First Koi: Varieties & Grading Explained

Several koi varieties showing different colors and patterns

Understanding Koi Varieties

Part of the joy of koi keeping is appreciating the artistry behind each variety. Here are the classics you'll encounter most often.

The Gosanke (The 'Big Three')

  • Kohaku — white body with red (hi) markings. The most iconic koi. See our Kohaku and Doitsu Kohaku currently in stock.
  • Taisho Sanke — white with red and black (sumi) accents. (Currently unavailable — rotates seasonally.)
  • Showa Sanshoku — black body wrapped with red and white. We stock Showa, Gin Rin Showa and Kin Ki Showa.

Other varieties we love

  • Chagoi — the friendliest koi; grows huge and becomes hand-tame. We usually stock several sizes of Gin Rin Chagoi.
  • Kujaku — metallic "peacock" with a matsuba pattern under vivid red. Both standard and Doitsu Kujaku often available.
  • Asagi & Shusui — indigo-blue traditional varieties with red on cheeks & belly. See our Gin Rin Asagi and Shusui.
  • Goshiki — five-colour koi that deepen beautifully with age.
  • Shiro Utsuri — dramatic jet-black with pure-white pattern.
  • Tancho Kohaku — pure-white koi with a single red circle on the head.
  • Benigoi — solid deep-red "flame" of the pond.

What Does 'Grade' Mean?

Grade reflects overall quality — the crispness of colour, the balance and edges of the pattern, body conformation, and skin lustre. Higher-grade koi show sharper, more deliberate patterning and superior body shape. Grade affects price, but the 'best' koi is ultimately the one that speaks to you.

Buying Tips for Beginners

  • Start with hardy, forgiving varieties as you learn water management.
  • Buy from a seller who quarantines and health-checks their fish.
  • Always request a photo or video of your specific koi before it ships.
