Medaka Sarasa Orange and White are attractive Japanese rice fish known for their bright orange and white colouring. Their small size, peaceful nature and easy care make them a popular choice for planted aquariums, outdoor tubs and small ponds. They are active, hardy fish that look especially striking when kept in a group.
A minimum aquarium size of 20 litres is suitable for a small group. A larger aquarium is recommended for bigger groups and provides additional swimming space while helping keep water conditions stable. They can also be kept in outdoor tubs and ponds with suitable protection from predators.
Medaka Sarasa Orange and White are peaceful fish and can be kept with other small, calm species.
Avoid large or aggressive fish that may chase or eat them.
Feed a quality small fish food, such as finely crushed flakes or small pellets. They also enjoy occasional live or frozen foods, including daphnia and baby brine shrimp. Feed small portions once or twice daily and avoid overfeeding.
Choose gentle filtration that keeps the water clean without creating a strong current. A sponge filter is ideal for smaller aquariums and provides gentle water movement.
Plants are recommended as they provide shelter and natural cover. Java moss, hornwort and floating plants are suitable choices and also provide surfaces for eggs.
Moderate aquarium lighting will help show off the orange and white colouring. Keep the lights on a consistent schedule with a period of darkness each day.
A heater is usually unnecessary when the aquarium remains within a suitable temperature range. Medaka are adaptable fish, but sudden temperature changes should be avoided.
Sand or fine gravel can be used. A darker substrate can provide a strong contrast and help the orange and white colours stand out.
Use smooth stones, wood and plenty of plants to create a natural environment. Leave open areas for swimming while providing enough cover for the fish to feel secure.
