Youkihi Medaka (Orange Japanese Ricefish) – Brilliant Color for Ponds and Nano Aquariums
The Youkihi Medaka, or Orange Japanese Ricefish, is a vibrant, selectively bred strain of Oryzias latipes that displays a rich orange body with a soft, luminous glow. Its name, "Youkihi" (楊貴妃), comes from the famed imperial consort known for her beauty — fitting for one of the most striking Medaka varieties available.
These fish are small, peaceful, and extremely hardy, thriving in both indoor aquariums and outdoor ponds or tubs. Their intense color is most vivid under natural sunlight or high-quality LED lighting, making them a favorite for mini ponds, patio setups, or aquascapes where contrast and movement are key.
