About

The horyu is a Japanese variety that gathers four traits in one fish: a blue-cast body, pearl scales, telescope eyes and head growth. It was created by Mr Sakaki, honorary chairman of the Horyu Aikoukai, who from 1968 worked from the ranryu seiga-chotogyo, a black-blue telescope-eyed oranda with head growth, crossing in a red-and-white crown pearl. It was first entered in competition at the inaugural Japan Number One Goldfish Show in 1994. The name joins Ako in Hyogo Prefecture, the breeder's home city, and the ear of rice, with the dragon of the ryugan telescope. The pairing of blue body colour with pearl scales is scarcely seen even in China. The association defines colour classes such as koryu, ranryu, saranryu, kokubyakuryu and hagoromoryu, and groups derived lines as kawari-ryu.

Morphs (Varieties)

Goldfish varieties arose from fixed mutations and selective breeding, and body form, tail form, scale type, colour and head growth are all carried forward by selection over generations. Inheritance is therefore shown as line-bred throughout rather than split into dominant and recessive.
