Overview

A Tarumi Bronze/Green-family development noted for blue-green fin light reminiscent of tropical seawater. The gallery credits Masaharu Tarumi as creator credited for selected fin-reflection development. The distinction between creator, house-line selector and older parent-stock developers remains important.

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

Known research gaps

  • Emerald Fin is not the same named line as Savanna's Emerald Moon.
  • Original-source breeder narratives cannot authenticate the actual fish sold under the label or establish Mendelian inheritance.
  • A complete first-sale timeline, actual mating and selected-generation logs, licensed photographs and independent secondary review are unavailable.
