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. It is a variety whose delicate shimmer you can enjoy up close in an aquarium.

7 things to know before welcoming a Ouhi
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.
2Body Glow and Fin Glow
Ouhi's defining trait is combining body glow, fin glow, and scale glow all at once. The way the glow and coloring show up varies from fish to fish, and comparing each individual's shimmer is part of the enjoyment.
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.
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.
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.
6Make Sure Food Reaches Every Fish
Ouhi is an albino with red eyes and weak eyesight, so it can have trouble seeing food. Take care that food reaches every fish, and keep it in a bright spot out of overly strong direct sunlight.
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.
