Overview
The source credits Sugita and reports an early Ginga Silver Hikari x Pure White breeding base, selected toward paler silver body color This is a historical creator/source record, not verified DNA or authenticated current broodstock.
Claim-by-claim evidence
| Research finding | Evidence class | Direct references |
|---|---|---|
| Specialist entry identifies Masahiro Sugita / 杉田正洋 as credited origin and lists 2013. | Specialist maker/year record; original registers independently uninspected | T052 ↗ |
| Creamy white Hikari body with contrasting yellow-toned fins | Source-described phenotype, not a standardized diagnostic or genotype test | T052 ↗ |
| The source credits Sugita and reports an early Ginga Silver Hikari x Pure White breeding base, selected toward paler silver body color | Published historical breeder account or attributed breeder-summary evidence | T052 ↗ |
| Silky/cream phenotype does not independently prove a single ci-gene cause in this selected fish | Differentiation and explicit breeding-evidence uncertainty | T052 ↗ |
Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Known research gaps
- Original parent-fish specimen identities, complete breeding ledgers and unambiguous first-sale dates remain unconfirmed.
- No molecular evidence establishes trait inheritance or the breeding uniformity of retail stock named for this variety.
- Photographs are source-owned and have not been rehosted; licensing review and photographer attribution are pending.
