Overview
Hikari-body branch of Tarumi's original long-fin line, described with particularly prominent dorsal-fin length. 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 — Developer of Hikari form of his earlier Tarumi Long Fin. | Breeder-submitted role, separate from original source-stock creators | JMU ↗ |
| The creator gallery identifies this as the Hikari-body-form version of Tarumi Long Fin and cites Aqua Life November 2018 coverage; the magazine month is not a verified first sale. | First-person breeding/selection account; publication and sale chronology not independently complete | JMU ↗ |
| Long dorsal and other ornamental fins in Hikari-type body form, especially suited to side viewing. | Observed or intended visual selection; not a genetic trait test | JMU ↗ |
| This is a different named morphology from Tarumi Long Fin base, but not proof of an independently new molecular strain. | 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.
