The wakin is a common goldfish with a divided, fantail-like tail and is the common goldfish of the Far East, particularly in Japan; in fact, our Western common goldfish with wild-type, single fins all round is uncommon in the Far East. These fish can grow large; those in the three pictures of Hong Kong fish in 2000 were over 10 inches (25 cm) in length when photographed.
There is a variety called the watonai which is intermediate between the wakin and the ryukin.
The British standard for the wakin is under development and should be published in early 2010.
The body and finnage are as for the common goldfish except that the body is shorter and the anal fin and the tail are divided; the tail is carried a bit flatter than in the fantail goldfish. The colour is possibly metallic only; anyone who has seen calico wakins is invited to contact the Website Author.
