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.
