Overview

A Tanaka-created white-background Morpho fin-form selected line. The evidence below is based on a documented specialist variety entry, not independently verified laboratory genetics.

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

Known research gaps

  • No independently inspected original breeder register, genotype assay or complete individual parent-fish mating ledger is available.
  • Source attribution and the historical year should not be interpreted as confirmed first retail sale date or authentication of present-day fish.
  • External catalogue images are not republished without separately verified copyright/reuse permission.
