Overview

Hikari-body branch of Tarumi's original long-fin line, described with particularly prominent dorsal-fin length. This account distinguishes original founder varieties, named selected variants, and unfinished breeder projects.

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

Known research gaps

  • Fish-specific parent identifiers, stock provenance, and any complete breeding generation log are not independently verified.
  • DNA causation, segregation ratios, phenotype stability across breeders and first commercial sale year are unverified.
  • Third-party fish photos cannot be reused without creator or rights-holder permission.
