Morpho Kikyou – モルフォ桔梗

No Comments

The Morpho Kikyou Medaka (モルフォ桔梗メダカ) is an exquisite ornamental fish that seamlessly combines the distinctive traits of the Mizuiro Kikyou and Morpho strains. This fusion results in a medaka variety that captivates enthusiasts with its ethereal beauty and graceful presence. Origin and Development: The development of the Morpho Kikyou Medaka was pioneered by breeder Shoichiro Hirokawa, who initially created the Mizuiro Kikyou strain—a blue-bodied medaka with elongated fins and a strong dorsal iridescence. To enhance its allure, Hirokawa introduced the fin-specific luminescence characteristic of the Morpho strain, achieved by crossing the Mizuiro Kikyou with an original lineage of Black Morpho Hikari-type medaka. Through meticulous selective breeding up to the F4 generation, individuals exhibiting both the elongated fins of the Mizuiro Kikyou and the radiant blue fin glow of the Morpho were stabilized, culminating in the creation of the Morpho Kikyou Medaka. Key Features: Breeding Insights: Achieving the harmonious blend of traits found in the Morpho Kikyou Medaka requires careful selection and breeding practices. Emphasis is placed on maintaining the balance between fin length and luminescence, ensuring that each generation retains the captivating features that define this strain. Conclusion: The Morpho Kikyou Medaka stands as a testament to the art of selective breeding, embodying a perfect synthesis of color, form, and luminescence. Its delicate blue body, complemented by glowing fins and elegant fin extensions, makes it a prized addition to any medaka enthusiast’s collection. Observing this fish as it glides through the water, its fins shimmering with a gentle blue light, evokes the enchanting image of a Morpho butterfly in flight—a truly mesmerizing spectacle.
