Mehina

Mehina is an elegant ornamental medaka with a soft pink body accented by vivid orange-red highlights, evoking the refined beauty of a traditional Japanese doll. Its delicate color gradation gives it a distinctly Japanese charm, and the coloring stands out most beautifully when viewed from above in a white container. Mehina has a calm temperament and gets along well with other medaka, though maintaining its signature coloring calls for some experience with water quality management and careful selection, which is why it's considered a variety for intermediate keepers. It typically lives 2 to 3 years and reaches an adult size of about 3 to 4 cm, a standard size for medaka. With a well-maintained environment, keepers can enjoy watching its subtle color changes for years to come.

About Mehina

Mehina is an elegant medaka with soft pink coloring and vivid orange-red accents, best appreciated from above in a white container. Living 2-3 years and growing to 3-4 cm, it's a variety suited to intermediate keepers.

7 things to know before welcoming a Mehina

  1. 1Best Viewed in White

    Mehina's soft pink and orange-red coloring shows to best effect when viewed from above in a white container. In a black container the colors can look quite different, so choosing the right container matters if you want to fully enjoy its coloring.

  2. 2Best for Intermediate Keepers

    Basic care for Mehina isn't especially difficult, but keeping its coloring vibrant calls for attentive water quality management and regular observation. Keepers who already have some medaka experience tend to enjoy watching its color development the most.

  3. 3Calm and Peaceful Temperament

    Mehina has a gentle temperament and mixes well with other medaka. However, crossbreeding with differently colored varieties can dilute Mehina's characteristic coloring in future generations, so keeping it separately is best if you want to preserve the line.

  4. 4Lifespan of 2-3 Years

    Mehina typically lives around 2 to 3 years. Keeping water temperature and quality stable helps it stay healthy over its full lifespan, so pay extra attention to temperature swings during seasonal changes.

  5. 5Grows to 3-4 cm as Adult

    Adults reach about 3 to 4 cm in length. Overcrowding can worsen water quality and dull coloring, so make sure your container size matches the number of fish you keep.

  6. 6Sensitive to Water Changes

    As with ornamental medaka in general, sudden changes in water quality or temperature can be stressful for Mehina. Take time to acclimate new arrivals gradually to their new environment.

  7. 7Prepare Your Tank First

    Before bringing your Mehina home, prepare a tank, dechlorinated water, and plants or hiding spots in advance. Choosing a white container from the start lets you enjoy Mehina's true coloring right away.
