About
The Watonai is a Japanese hybrid goldfish created by crossing the Wakin with the Ryukin (or Oranda). Its name is said to derive from Watonai, the protagonist of the classic Bunraku and Kabuki play "Kokusenya Kassen." The breed inherits the Wakin's streamlined, active body form while adding the Ryukin's elegant bifurcated double tail, resulting in a fish that is both agile and graceful. Common colors include red, white, sarasa, and calico. Its strong appetite and active swimming nature mean it should not be housed with slow-moving fancy varieties. Spacious tanks of 60 liters or more or outdoor ponds are ideal.
