MEDAKAPEDIA / BATCH 006
Ten historical varieties.
Attribution matters.
Ten documented Japanese ornamental Medaka histories spanning a 2012–2018 specialist chronology: transparent-scale patterns, split-fin and Swallow body types, Shinkai and Orochi Lame. Each profile includes Japanese names, original creator credit where recorded, source-linked phenotype and lineage distinctions, and explicit research gaps.
These are archival accounts, not ten independently DNA-confirmed strains. Unknown authorship is preserved as unknown.
