Oryzias latipes var.
Premium medaka variety combining multiple colors in harmonious patterns. Often selectively paired color morphs, demanding higher husbandry expertise. Sophisticated aesthetic ideal for experienced enthusiasts.
The Mariage group is a collective name for premium improved varieties in which multiple colors blend harmoniously. Many strains cross several distinctive traits — long fins, external light, lame, clear scales — so that colors and features seem to be 'married' together, which is said to be the origin of the name. Their elegant, layered appearance appeals to hobbyists who enjoy careful observation. Found in standard and long-fin body types, roughly 3–4 cm. Strains carrying multiple traits are somewhat genetically unstable, so fixing and maintaining the desired features benefits from selective-breeding experience, making the variety somewhat more demanding. Color and external light show best in dark containers under bright light. Peaceful and community-compatible.
The Mariage lives 2-3 years.
The Mariage grows to 3-4cm.
The ideal water temperature for the Mariage is 18〜24℃.
