Kinshu Medaka
Kinshu is a kin-type medaka with a reddish-brown base deeper than orange, marked with mottled patches known as buchi. Its name evokes autumn, when leaves glow like woven brocade, and its calm reddish-brown tones are the main draw. It is also called Orange Kin. It is a small medaka, and the difficulty level is beginner-friendly. Medaka are generally gentle fish that swim together in groups, and the mottling differs from fish to fish, so choosing a favorite is part of the fun. The contrast of patches on the reddish-brown base sits comfortably beside plants and driftwood.

7 things to know before welcoming a Kinshu Medaka
1Beginner-Friendly Care
Kinshu is rated beginner-friendly. What matters most is not special equipment but the basics: keeping the water clean, not overfeeding, and avoiding sudden changes. If you are new to fishkeeping, it is a manageable variety once you have those basics down.
2Patterns Vary by Fish
The depth of the reddish-brown and the way the patches appear differ from fish to fish. Check the photos and descriptions in each listing, and ask the breeder if anything is unclear. Colors on a screen can also look a little different in person.
3Preparing Tank and Water
Kinshu is a small fish, but a container with room to spare for the number of fish keeps the water more stable. Treat tap water to remove chlorine and have it ready before the fish arrive. Plants and hiding spots can help them settle in.
4Showing Off the Color
How the reddish-brown looks depends on the background and container color. Lighter containers or substrate tend to make the calm tones stand out. Try viewing from above and from the side to find the angle you like best.
5Temperament and Tankmates
Medaka are generally gentle and appealing when kept in a group. They usually get along with other calm medaka of similar size, but avoid keeping them with fish large enough to swallow them or with aggressive species.
6Feeding and Water Changes
Feed only what the fish can finish in a short time and remove any leftovers. Rather than replacing all the water at once, change it gradually with water that has been left to stand, which avoids abrupt shifts. Strong direct sunlight can warm the water quickly, so choose the spot with care.
7Acclimation and Health Checks
When the fish first arrive, float the bag in the water to match the temperature, then add a little of your tank water at a time. After that, watch for changes such as clamped fins, staying motionless, or refusing food. If something seems off, review the water and setup, and consider moving the fish to a separate container to observe.
