About medaka

The medaka category on Bree-Choku lets you welcome a wide variety of improved medaka — such as Youkihi and Miyuki strains — directly from the breeders who raised them. Medaka are hardy, tolerate a broad temperature range, and can be kept in an indoor tank or an outdoor container, with breeding that is easy to enjoy. Even beginners can choose a favorite strain after learning the basics of water management, feeding, and getting through summer and winter.

7 things to know before welcoming a medaka

1. 1Decide whether to keep them indoors or outdoors

   Medaka can be kept in an indoor tank or in an outdoor water bowl or plastic container. Outdoors, natural light brings out their colors and you can enjoy a planted biotope, but you must manage temperature swings and predators. Decide on a location before welcoming them, to match your keeping style.

2. 2Maintain the environment with water quality and water changes

   Medaka are hardy, but uneaten food and waste foul the water and harm their health. Keep a number suited to the container size and make regular partial water changes. Outdoors, plants and bacteria help with water quality. When refilling, match temperature and avoid sudden changes.

3. 3Provide moderate sunlight and watch temperature

   Sunlight helps keep medaka healthy and colorful, but direct summer sun can overheat the water. Provide shade outdoors and supplement brightness with lighting indoors. Avoiding sudden temperature changes and keeping a moderate environment is the key to raising them well.

4. 4Know about breeding and raising fry

   Medaka spawn readily from spring into summer as the water warms. Eggs can be eaten by adults, so moving the spawning mop to a separate container is safer. Fry have tiny mouths, so feed them fine, dedicated food frequently. Breeding is one of the great joys of keeping medaka.

5. 5Prepare for summer and winter

   Medaka tolerate a wide temperature range, but high summer and low winter temperatures still need care. In summer, use shade and ample water volume to limit heating; in winter outdoors, use a container deep enough that the surface does not freeze, feed sparingly, and let them overwinter quietly.

6. 6Understand the colors and features of each strain

   Medaka have been extensively improved, with strains in red, white, blue, and types showing glitter or iridescence. Basic care is common across strains, but colors look different depending on lighting and container color. Choose a favorite strain and set up an environment that shows it off.

7. 7Estimate startup and ongoing costs

   Medaka keeping is appealing because the startup cost of containers, plants, and substrate is relatively modest. Ongoing costs include food, water conditioners, and indoor lighting electricity. Numbers can grow through breeding, so plan with room to add containers.
