Lineage review · Batch 23: Historical source describes the breeding stock or selected form shown by dashed connections. This does not establish individual parentage, genotype, or dominance. Original specialist source ↗

Lineage review · Batch 016: The reviewed sources do not establish a defensible specific parent mating; the illustrated pedigree intentionally remains disconnected. Review Japanese specialist record ↗

Overview

This is an original breeder-catalogue named morphology selection, not a separate genetic founder. Dark-bodied small-eye selection with gold-colored fins and the Hikari silhouette.

Known research gaps

  • Breeder parent fish IDs and the exact crosses introducing the chosen Hikari/Daruma body form are not available in the cited public source.
  • No independent allele, genotype, Mendelian fixation ratio or current breeder-authenticated retail stock claim is established.
  • Source-owned photos are not reused without explicit rights permission.
