Overview

The historic transparent-scale Tancho line is a white-bodied fish with vermilion-orange coloring concentrated around the head. The original creator is not identified in this historical catalog; do not infer one. The 2012 historical variety group is a documentary context, not proof of the first sale.

This recorded selected pattern is not a cross with koi and does not imply verified founder ancestry for any modern retail fish. Documented in the 2012 historical variety group.Editorial interpretation bound to historical catalog contextH12 ↗

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.
