Overview

Aurora Miyuki combines an Aurora-type translucent appearance with Miyuki exterior-light features. The breeder's own visual family tree explicitly omits many intermediate crosses. Documented developer/creator role: JOURAKUAN / 静楽庵.

Recorded lineage inputs

Blue Miyuki / Dorsalfinless blue Medaka

These are historical breeder-reported founder inputs or longer selection stages, not individually sequenced parents. Review the source J02 for its original scope and missing generations.

Known research gaps

  • Exact release date and original parent fish identities are not independently certified.
  • Do not infer molecular dominance or fixed inheritance from a schematic breeder tree.
  • 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.
