The catalog reports Black Diamond × Black Lame Miyuki Sapphire lines, named Blue Moon after F4 selection.

Overview

Savanna describes reducing excessive black appearance while displaying blue Sapphire-family lame clearly from a top view. The catalog is a first-party account, not independent genetic confirmation.

Breeder-reported lineage and selection

The dashed arrows map reported inputs, not independently authenticated parent pairs. Multi-stage inputs are shown together for readability; this is not a verified single-generation mating plan.

Dashed connectors show breeder-reported input or selection history; they do not prove actual parent pairs, alleles, or dominance. Parent fish IDs are not independently established.

Source: Savanna Vol.1, printed p.14. Dashed means breeder-reported; the original source alone does not prove inherited traits.

Known research gaps

  • F4 designation alone does not establish biological fixation or inheritance ratios.
  • Blue Moon and Blue Moon Earth Eye must remain distinct named expressions without an inferred extra genetic cross.
  • No independent DNA-verified inheritance, controlled water-parameter optimum, graded phenotype guarantee or offspring ratio is established.
  • Third-party catalog photos are not licensed for republication in this entry.
