About
The Edonishiki is a Japanese goldfish variety created by crossing the Azuma Nishiki (an Oranda-type calico) with the Ranchu, resulting in a fish that has the Ranchu's egg-shaped, dorsal-finless body combined with the vibrant calico coloration of nacreous tricolor scales. Developed and refined in Tokyo (historically known as Edo), the breed's name reflects its origins. The complex interplay of red, white, black, and blue tones across its translucent scales makes each Edonishiki unique. Like the Ranchu, it is best appreciated from above, where the symmetry of its body and the beauty of its pattern are most apparent. Care requirements closely follow those of the Ranchu: shallow tanks or traditional viewing bowls, minimal water flow, and careful feeding to prevent swim bladder issues.

Morphs (Varieties)
Goldfish varieties are line-bred for body shape, tail type, scale type, and coloration. Traits such as protruding eyes, transparent scales (calico), and albinism are single-locus traits.
RecessiveVisual only with two copies; one copy = het (carrier).
Calico (mosaic transparent scale)
PolygenicContinuous trait from multiple genes; intensified by selective breeding.
