Medaka Care Basics Review
Before exploring varieties, let's quickly cover the fundamentals every beginner should know.
Medaka are hardy fish capable of surviving in water temperatures between 5–35°C, though they're sensitive to sudden temperature changes. The ideal range is 18–28°C, and they can be kept equally well in outdoor biotopes (like water lily pots) or indoor tanks. Pay special attention to high summer temperatures—see our high-temperature care guide for outdoor medaka for more details.
Water volume guideline: 1 liter per medaka
Water change frequency: Weekly, replacing about 1/3 of the water
Feeding frequency: Once or twice daily, only as much as they can eat in 2–3 minutes
Filter type: A sponge filter or submersible filter works perfectly
Keep these points in mind, and you'll be ready to start with confidence. Now let's move on to variety selection.

Variety 1: Yangguifei (楊貴妃)
Difficulty: ★☆☆☆☆ / Price range: ¥200–500
The Yangguifei is the oldest and still the most beloved of all cultivated medaka varieties. True to its name, its defining feature is a gorgeous deep red body color that makes it a stunning ornamental fish when swimming through the water.
The Yangguifei's greatest strength is its exceptional hardiness. Despite being a cultivated variety, it retains the robust vitality of wild medaka, tolerating water quality and temperature fluctuations well. Even if a beginner makes minor care mistakes, these resilient fish usually bounce back.
Care Tips
Outdoor exposure to sunlight intensifies its red coloration
Breeding is straightforward—they often spawn daily during spring and summer
Use color-enhancing pellets to bring out even richer red tones
Affordable and widely available at pet shops and garden centers, the Yangguifei is the quintessential starter variety.

Variety 2: Miyu (幹之)
Difficulty: ★☆☆☆☆ / Price range: ¥200–800
The Miyu's defining characteristic is the shimmering silver iridescent stripe running down its back (iridophore layer). The way it glitters in the light is mesmerizing—like a living jewel swimming through water. It's one of the flagship varieties that sparked the cultivated medaka boom.
Iridescent grading ranges from "half-daruma" to "full-body," with full-body individuals (where the shimmer extends from back to tail base) being particularly prized. Beginners should start with standard specimens before pursuing higher grades.
Care Tips
Black containers make the iridescence most visible and striking
When breeding, pairing high-shine parents produces offspring with stronger iridescence
Price varies significantly by grade—choose according to your budget
---
Variety 3: White Medaka (白メダカ)
Difficulty: ★☆☆☆☆ / Price range: ¥100–300
White Medaka are among the most accessible and affordable cultivated varieties. Unlike albinos lacking pigment, these carry true white pigmentation with black eyes.
Their pure white, simple coloring complements any container setup beautifully. Whether displayed in a lush biotope with water lilies and aquatic plants or in a minimalist tank, they offer a clean, elegant aesthetic.
Care Tips
Works in any container color—versatile and foolproof styling
Related to wild species, they adapt readily to environmental changes
Mix easily with other varieties—perfect as your collection's foundation
---
Variety 4: Blue Medaka (青メダカ)
Difficulty: ★☆☆☆☆ / Price range: ¥100–300
Blue Medaka share the pale coloring of White Medaka but display a delicate blue-tinted shimmer depending on the light angle. Don't underestimate their subtlety—watching them glide through the water brings a refreshing, cool elegance that never gets old.
Hardiness matches White Medaka, making it among the easiest varieties to keep. Combine white, blue, and Yangguifei together for a colorful, visually striking biotope display.
Care Tips
Sunlight enhances the blue iridescence
Pair with White Medaka to compare and contrast their colors
Ideal for your first breeding attempts—spawn readily
---
Variety 5: Yangguifei Lame (楊貴妃ラメ)
Difficulty: ★★☆☆☆ / Price range: ¥500–2,000
This luxurious variety combines the Yangguifei's signature red coloring with glitter-like sparkles scattered across the scales. Every movement catches light, creating a dazzling display that epitomizes ornamental fish beauty.
Based on the hardy Yangguifei, it's still manageable for beginners, though pricier than standard red or blue varieties. Given its spectacular appearance, the value is well worth it. Higher glitter density commands higher prices. As of 2026, cultivated variety diversity has expanded dramatically, offering unprecedented choices.
Care Tips
Black containers showcase the glitter most effectively
For breeding sparkly offspring, pair parents with abundant lame (glitter)
Avoid intense direct sunlight; an environment mixing shade and partial light ensures longevity
