Yamabuki

Yamabuki medaka are prized for their bright, lemon-yellow body color — known in Japanese as "yamabuki iro" — which reads as even brighter than the classic Yohki medaka. Their calm, gentle temperament makes them easy to keep alongside other medaka, and their small adult size of 2 to 4 cm gives them a graceful presence in any tank or water lily bowl. They readily eat both prepared fish food and daphnia, and their hardy nature makes them a great pick for beginners. With a typical lifespan of 2 to 3 years, Yamabuki offer years of enjoyment as their color shifts gently with the seasons.

About Yamabuki

Yamabuki medaka are a beginner-friendly variety known for their bright lemon-yellow color and calm, hardy nature. Adults reach 2-4cm and typically live 2-3 years. Here are key care tips and FAQs.

7 things to know before welcoming a Yamabuki

  1. 1Sunlight Enhances Color

    Yamabuki's signature bright yellow tends to look more vivid with moderate exposure to natural sunlight. Keeping them outdoors or in a well-lit spot can help bring out their best coloring.

  2. 2Calm and Sociable

    Yamabuki medaka have a gentle temperament and generally get along well with other medaka varieties and small fish. Their low aggression makes them a good choice if you want to keep several varieties together.

  3. 3Feed Pellets and Daphnia

    They readily eat prepared fish food and also enjoy live foods like daphnia. Offering small amounts several times a day, only as much as they can finish, helps keep the water clean and the fish healthy.

  4. 4Water Changes Matter

    While medaka are hardy fish, a sudden drop in water quality can still cause health problems. Regular partial water changes help keep temperature and water conditions stable.

  5. 5Small Adult Size

    Yamabuki stay small even as adults, typically reaching only 2 to 4 cm. This makes them easy to keep in small tanks or water lily bowls, even with limited space.

  6. 6Lifespan of 2-3 Years

    Yamabuki medaka typically live around 2 to 3 years. Seasonal temperature changes and consistent daily care both play a role in how healthily they live out their lifespan.

  7. 7Acclimate Them Slowly

    A sudden change in water temperature or quality can stress newly introduced fish. Take time to gradually acclimate them to their new water before releasing them into the tank.
