Overview
The specialist reports selection from white-bodied Ouka family crossed with Ryokkou Longfin material 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 Medaka-ya Savanna / サバンナ as credited origin and lists 2021. | Specialist maker/year record; original registers independently uninspected | Z882 ↗ |
| Cream-white semi-transparent Aurora body with strong lame and head-fin optical reflection | Source-described phenotype, not a standardized diagnostic or genotype test | Z882 ↗ |
| The specialist reports selection from white-bodied Ouka family crossed with Ryokkou Longfin material | Published historical breeder account or attributed breeder-summary evidence | Z882 ↗ |
| This is not the same named stock as Savanna's Saboten or Emerald Moon, and source-derived crosses do not verify individual specimens | Differentiation and explicit breeding-evidence uncertainty | Z882 ↗ |
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.
