Overview

A Hikari-body Panda-eye line with dark-appearing eyes in a historically credited Medaka selection. The source associates Panda eyes with altered iridophore appearance, and notes that Hikari-body specimens can lack conspicuous dorsal shine. Creator-versus-discoverer status is source-scoped.

Dark-looking eye regions and often a dark belly accompany the Panda-eye pattern; Hikari form is a separate body characteristic.Visual phenotype only; individual expression can varyE78 ↗
The archive explicitly labels its illustrative image as a Panda rather than a Panda Hikari, so the photo is not proof of the Hikari body form. Historical context: 2007 historical catalog section.Editorial distinction grounded in cited source; exact sale dates not guaranteedE78 ↗

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

Known research gaps

  • A suggested iridophore mechanism is not supported by an individual molecular assay or a fixed sex ratio.
  • Cited first-generation and selected-parent statements do not prove DNA genotype, inheritance rate or present-day breeder-stock identity.
  • No third-party breeder/catalogue image is reproduced; photo rights and original genetic records require independent review.
