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.

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.
