Overview
A line known for extended, branching fins and reflective fin effects. Parentage here describes the published breeder history; it is not a tested genetic model.
Claim-by-claim evidence
| Research finding | Evidence class | Direct references |
|---|---|---|
| Tarumi is credited by the breeder group's gallery as creator of Mariage Long Fin | Breeder-group attribution | T1 ↗ |
| The breeder group's account names Rinkou Long Fin × Morpho as the reported foundation | Breeder-described cross | T1 ↗ T4 ↗ |
| Fin elongation and branching are its described visible traits | Observed/catalog phenotype description | T1 ↗ T5 ↗ |
| The 2021 catalog year for Mariage Kissing Wide Fin must not be treated as the original Mariage Long Fin release year | Variant/date distinction | T4 ↗ |
Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Known research gaps
- No DNA-confirmed alleles, Mendelian ratios or universally accepted grading thresholds supplied by these sources.
- The first release date of the original Long Fin should remain separately unverified.
- Trait expression differs by individual fish; appearance does not prove ancestry.
