Yozakura

About Yozakura

Yozakura medaka is a relatively modern variety developed by crossing established selectively bred lines such as "Miyuki" and tricolor body-outer light strains. Its deep black body is scattered with cherry-pink, gold, and white lame, overlaid with body-outer light that gleams along the edges of the body, causing its appearance to shift subtly with every change of angle or lighting. This ethereal quality reminded breeders of cherry blossoms floating against a night sky, giving the variety its evocative name. Because lame density, distribution, and the reach of the body-outer light differ from fish to fish, no two individuals are identical even within the same lineage—a quality that fascinates collectors. Despite its striking looks, Yozakura is hardy and easy to keep, requiring no more care than standard medaka varieties, and thrives in everything from outdoor biotopes to indoor aquariums. Paired with a dark substrate or container, its lame reaches peak visual impact, making it a popular choice as living decor.

7 things to know before welcoming a Yozakura

1. 1Lamine Varies with Temperature

   The lamine sparkle of Yozakura can shift in intensity depending on water temperature and tank conditions. Keeping water between 18–26°C helps stabilize coloration, while overly cold water may cause the lamine to appear dull. Check water temperature regularly during seasonal changes.

2. 2Black Containers Enhance Color

   Yozakura's coloration stands out most vividly when kept in black or dark-colored containers, which enhance the contrast of lamine and pink hues. Transparent or white containers often make the colors appear washed out. Black mortar tubs or dark-glazed pottery bowls are popular choices for display.

3. 3Suitable for Indoor and Outdoor Keeping

   Yozakura adapts well to both outdoor biotope setups and indoor aquariums. Sunlight brings out the full brilliance of the lamine in outdoor settings, while LED lighting can highlight the external body reflections indoors. In either environment, maintaining good water quality is key to keeping fish healthy.

4. 4High Variation Between Individuals

   Yozakura individuals vary considerably in lamine density, pink coloration, and the expression of external light patterns. Part of the fun is selecting fish that match your personal aesthetic. Even offspring from the same parents can differ widely in markings, which is why many enthusiasts enjoy the process of selective breeding across generations.

5. 5Best Bred in Spring and Summer

   Yozakura breeds best when water temperature exceeds 20°C and daylight exposure reaches around 13 hours or more, making spring and early summer the prime season. Females can spawn daily during this period. Since eggs may be eaten by adults, using spawning mops or aquatic plants and moving eggs to a separate container will improve hatching rates.

6. 6Fry Require Careful Raising

   Yozakura fry are small and sensitive to water quality changes and strong currents. Use gentle aeration and feed specialized fry food or finely crushed flakes to improve survival rates after hatching. Keep fry in a separate container until they reach about 1 cm in length, as adults may eat them if housed together.

7. 7Price Reflects Quality Variation

   Yozakura's popularity has increased availability, with prices ranging from a few hundred to several thousand yen depending on lamine density, external light strength, and overall pattern quality. It is important to understand what you are paying for before purchasing. Buying directly from breeders often provides access to pedigree-tracked or selectively bred individuals for those prioritizing quality.
