Medaka strainEvidence by claimIndependent review ongoing

JOURAKUAN says sales of its tricolor-lame exterior-light selection began in spring 2018, followed by WI-01 and WI-03 selected house stock codes.

Evidence labels refer to documentary strength. They do not assert independently tested genetics.

Known research gaps

  • Do not treat breeder-reported expression percentages as a guarantee for buyers or genetics proof.
  • Historical 2018 first sale applies to the exterior-light expression, not all tricolor-lame fish.
  • 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.
