Overview
The breeder gallery describes Kirameki × Matsui longfin for a Kirameki-patterned elongated-fin selection. The gallery credits Masaharu Tarumi as creator credited for selected longfin derivative. The distinction between creator, house-line selector and older parent-stock developers remains important.
Claim-by-claim evidence
| Research finding | Evidence class | Direct references |
|---|---|---|
| Breeder credit: Masaharu Tarumi, described as creator credited for selected longfin derivative. | Breeder-submitted first-party report; independent corroboration pending | G1 ↗ |
| Reported selection inputs or ancestry: Kirameki × Matsui longfin (reported creator cross). | Breeder-described genealogy; not a molecular pedigree | G1 ↗ |
| Reported appearance or target expression: Kirameki body coloration with Matsui-type long fins, suitable for side viewing. | Breeder phenotype description; not a standardized diagnostic test | G1 ↗ |
| The breeder gallery cites Aqua Life November 2018 as magazine coverage; not a proven founding date. | Date scope: gallery or cited magazine context only | G1 ↗ |
Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Known research gaps
- Distinguish the documented Matsui longfin derivative from every house selection named Kirameki.
- Original-source breeder narratives cannot authenticate the actual fish sold under the label or establish Mendelian inheritance.
- A complete first-sale timeline, actual mating and selected-generation logs, licensed photographs and independent secondary review are unavailable.
