About Tricolor

Sanshoku medaka emerged from Japan's selective breeding boom as a variety celebrated for its intricate blending of white, red (orange), and black—sometimes called a "swimming work of art." Medaka were once a plain, understated small fish, but decades of careful selection by dedicated hobbyists gave rise to the rich variety of patterned strains seen today. Because the tricolor pattern forms randomly, no two individuals are identical, and the search for a personally appealing fish is part of the appeal. Temperamentally peaceful and physically hardy, sanshoku adapt well to environments ranging from outdoor lotus bowls to indoor aquariums. Stable water temperature, adequate light, and dark-colored containers help the colors show at their best. Breeding is relatively straightforward, and watching the distinct patterns that emerge in each new generation adds another layer of long-term enjoyment.

7 things to know before welcoming a Tricolor

1. 1Each Fish Has Unique Markings

   No two sanshoku medaka share identical markings, even from the same parents. When purchasing, inspect each fish carefully to find your preferred pattern. Note that colors and markings can shift as the fish matures, so watching them develop is part of the enjoyment.

2. 2Tolerate a Wide Temperature Range

   Sanshoku medaka can tolerate water temperatures roughly between 5°C and 30°C, but sudden swings are stressful and can lead to illness. Guard against overheating from direct summer sun and freezing in winter. Reviewing your setup each season helps keep them healthy year-round.

3. 3Color-Enhancing Foods Make a Difference

   The red and black pigmentation of sanshoku can be enhanced with color-boosting foods containing carotenoids or spirulina. Standard medaka pellets are fine for basic care, but adding a color-enhancing food can bring out their best appearance. Feed twice daily in amounts consumed within two to three minutes to avoid water quality issues.

4. 4Outdoor Keeping Enhances Color

   Natural sunlight intensifies the colors of sanshoku medaka, making outdoor setups in lotus bowls or tubs particularly rewarding. Aquatic plants and floating plants complement them beautifully. Do not forget to place a net over the container to protect the fish from cats and wild birds.

5. 5Choose Tank Mates of Similar Size

   Sanshoku medaka are peaceful and get along well with other medaka varieties. However, significant size differences can lead to smaller fish being nipped, so keep fish of similar size together. Avoid housing them with goldfish or other large-mouthed fish that may prey on them.

6. 6Use a Spawning Mop for Breeding

   Sanshoku medaka begin spawning when water temperature exceeds 18°C and daylight reaches about 13 hours. Eggs are often eaten by adults, so use a spawning mop or aquatic plant and move the eggs to a separate container to improve hatch rates. Raise the fry on finely ground, dedicated fry food.

7. 7Starter Costs Begin Around a Few Thousand Yen

   A basic sanshoku medaka setup including a container, substrate, plants, and food can be assembled for a few thousand yen. Premium individuals with exceptional coloration or body types can range from several thousand to tens of thousands of yen each, so choose a source that fits your budget. Ongoing monthly costs for electricity and food are generally a few hundred yen.
