Ouhi

Ouhi is a gorgeous improved medaka variety built on an albino base, combining body glow, fin glow, and scale glow in one fish. Its coloring ranges from white to pale pink to red-and-white patterns, and the light extends elegantly all the way to the tips of its fins. Considered a variety best suited to experienced keepers, it tends to show its full beauty in the hands of someone who already has experience with improved medaka. Ouhi typically lives 2 to 3 years and reaches about 3 to 4 cm in body length as an adult. With a calm temperament, it's well suited to quiet observation, letting you appreciate its delicate shimmer up close.

Advanced
Lifespan
2-3 years
Size

Albino-based with body, fin and scale luster; colors range from white to pale pink, orange and red-and-white, and long-fin individuals also appear.
Care Tips

Water Quality & Temperature
Keep around 15-28°C; avoid summer overheating and sudden changes, and keep water stable.
Breeding
It can breed, but albino fry have lower early survival; feed fry fine food frequently and raise them carefully.
Cautions
It needs a little more care than other lines, being sensitive to underfeeding and strong light; long-fin individuals damage their fins easily.

About Ouhi

Ouhi is an improved medaka combining body, fin, and scale glow. Best for experienced keepers; lives 2-3 years, grows to 3-4 cm.

7 things to know before welcoming a Ouhi

  1. 1Best Suited to Experienced Keepers

    Ouhi is considered a variety best suited to experienced keepers. Maintaining stable water quality and temperature helps preserve its coloring and glow over time. It suits keepers who already have some background in medaka care.

  2. 2Body Glow and Fin Glow

    Ouhi's defining trait is combining body glow, fin glow, and scale glow all at once. Individual fish vary quite a bit in how the glow and coloring develop, and watching those changes unfold as the fish matures is part of the enjoyment.

  3. 3A Range of Color Variations

    Coloring ranges from white to pale pink to red-and-white patterns depending on the individual fish. Since no two Ouhi look quite alike, many keepers enjoy comparing colors across several fish at once.

  4. 4A Lifespan of About 2 to 3 Years

    Ouhi typically lives around 2 to 3 years. As a companion you'll care for over that span, keeping up with basic daily maintenance like water changes and temperature management supports its long-term health.

  5. 5A Compact Adult Size of 3 to 4 cm

    Even as an adult, Ouhi stays compact at about 3 to 4 cm in body length. That size makes it manageable in a relatively small setup, whether an indoor aquarium or an outdoor biotope-style container.

  6. 6Better Alone or with Its Own Kind

    To fully appreciate its glow and coloring, it's best to keep Ouhi on its own or alongside closely related varieties. Housing it with more active fish can make it harder to observe its color and shine clearly.

  7. 7Prepare Your Setup Before Bringing One Home

    Before bringing an Ouhi home, it's important to have your tank or container, along with your temperature and water quality management routine, already set up. Given that this variety is best suited to experienced keepers, thorough preparation beforehand makes a real difference.
