Overview

The source reports Goshiki development using Kurigami and Kuroho stock; Type R was selected out of later Goshiki breeding generations This is a historical creator/source record, not verified DNA or authenticated current broodstock.

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

Known research gaps

  • Original parent-fish specimen identities, complete breeding ledgers and unambiguous first-sale dates remain unconfirmed.
  • No molecular evidence establishes trait inheritance or the breeding uniformity of retail stock named for this variety.
  • Photographs are source-owned and have not been rehosted; licensing review and photographer attribution are pending.
