Overview

Oba's yellow-bodied Meller Medaka, known as Raijin, applies the divided-fin body form to yellow coloration. Historical catalog creator attribution: Yukio Oba / 大場幸雄 (Hiroshima). The 2012 historical variety group is a documentary context, not proof of the first sale.

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

Known research gaps

  • Precise commercial introduction dates, actual founder specimen IDs and complete generation-by-generation records are not fully documented in this catalog.
  • The named phenotype or historical breeding description is not a DNA-verified pedigree or a guaranteed inheritance ratio.
  • Current breeder-authenticated stock, precise strain-specific water parameters and photograph licensing remain unconfirmed.
