Overview
The breeder's named Hikari-body form of Mariage Kissing Wide Fin, rather than a new independently crossed founding stock. This account distinguishes original founder varieties, named selected variants, and unfinished breeder projects.
Claim-by-claim evidence
| Research finding | Evidence class | Direct references |
|---|---|---|
| Developer role: Masaharu Tarumi / 垂水政治 — Creator/selector of the Hikari form of an established wide-fin line. | Breeder-submitted role, separate from original source-stock creators | JMU ↗ |
| The Japan Medaka Universe gallery identifies the Hikari-bodied entry separately from the normal-body Mariage Kissing Wide Fin; it does not report a different direct-parent mating pair. | First-person breeding/selection account; publication and sale chronology not independently complete | JMU ↗ |
| Hikari body form combined with exceptionally broad dorsal/anal fins and modified fin-ray structure. | Observed or intended visual selection; not a genetic trait test | JMU ↗ |
| Do not count Hikari and normal-body records as two separate laboratory-authenticated original genes or invent extra founding crosses. | Lineage ambiguity or experimental development constraint | JMU ↗ |
Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Known research gaps
- Fish-specific parent identifiers, stock provenance, and any complete breeding generation log are not independently verified.
- DNA causation, segregation ratios, phenotype stability across breeders and first commercial sale year are unverified.
- Third-party fish photos cannot be reused without creator or rights-holder permission.
