Overview
Fuchigami describes developing a Real Long Fin expression from Ouhi (Albino Miyuki) crossed with Real Long Fin stock. The gallery credits Masayuki Fuchigami as breeder-submitted developer credit. 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
- Do not conflate Fuchigami's Ouhi Real Long Fin with Tarumi's Albino Ouhi bronze derivative.
- 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.
