Overview
The breeder sought a vivid red fin color together with deeper sapphire-blue lame. Its published cross is a breeder account, not molecular genotype verification. Documented developer/creator role: JOURAKUAN / 静楽庵.
Claim-by-claim evidence
| Research finding | Evidence class | Direct references |
|---|---|---|
| The official JOURAKUAN profile names Reiwa Black Lame Miyuki Sapphire-type stock × Neptune as the breeding foundation | Breeder-authored direct cross account | J04 ↗ |
| The breeder describes sustained selection across later generations | First-party selection statement, generations not specified | J04 ↗ |
| Strong sapphire-blue lame and red fins are stated appearance goals | Official breeder phenotype description | J04 ↗ |
| The profile does not establish the release year or exact founding fish identification | Date and traceability limitation | J04 ↗ |
Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Recorded lineage inputs
Reiwa Black Lame Miyuki Sapphire family / Neptune
These are historical breeder-reported founder inputs or longer selection stages, not individually sequenced parents. Review the source J04 for its original scope and missing generations.
Known research gaps
- The source does not authorize an inference about nucleotide variants controlling sapphire or fin color.
- Do not conflate parent Neptune's creator with the developer of the NOVA derivative.
- DNA-confirmed ancestry, Mendelian segregation, complete parent-pair registers and strain-specific water requirements are not established.
- Images from magazine, breeder sites and shop listings are not republished without verified reuse permission.
