Overview

This is an original breeder-catalogue named morphology selection, not a separate genetic founder. Dark, gold-finned small-eye selection in a compact Daruma body form.

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.
