关于婚配系

Mariage-kei is a selectively bred medaka variety developed by Japanese breeders over many years of refining tri-color bloodlines. The name "Mariage" (French for "marriage") evokes the festive harmony of vermilion, white, and black blending together on a single fish. Multiple lineages exist, including long-finned variants, and because each individual carries a unique pattern, the variety holds strong appeal for collectors. Temperament is gentle, making Mariage-kei suitable for both indoor aquariums and outdoor biotope setups. Keeping them in dark-colored containers enhances color contrast noticeably. Careful selection of parent fish with vivid, balanced markings allows the quality of patterning to improve across generations, rewarding breeders with increasingly striking results. This variety offers both the joy of breeding and high ornamental value.

迎接婚配系前需要了解的6件事

1. 1Color Expression Varies Widely

   Each Mariage-kei fish carries a unique distribution of red, white, and black, so no two look identical. Check live photos or breeder images carefully before purchasing, and keep in mind that the pattern can shift as the fish matures.

2. 2Ideal Temperature: 15–28°C

   Like most medaka, Mariage-kei thrive between 15°C and 28°C. Guard against summer overheating from direct sunlight and sudden winter temperature drops. Outdoors, adjust placement and shading with the seasons.

3. 3Slightly Alkaline Water Is Best

   A slightly alkaline pH of 7.0–7.5 suits Mariage-kei best. Adding a small amount of oyster shell helps stabilize pH. Perform partial water changes of about one-third weekly, and avoid sudden chemistry swings.

4. 4Dark Containers Enhance Color

   Using a black or deep-navy container makes the tri-color contrast pop, especially the red and white tones. White containers can wash out the colors, so choose dark vessels if you want the best visual impact.

5. 5Easy to Breed, Selection Matters

   Mariage-kei breed readily and lay eggs on aquatic plants or spawning mops. However, fry vary in color quality, so selecting parent fish with vivid, well-balanced patterns is key to producing attractive offspring over generations.

6. 6Cost Varies with Pattern Quality

   Prices range from a few hundred yen for entry-grade fish to several thousand yen or more for prized specimens with exceptional patterning. Budget around ¥10,000–¥20,000 upfront to cover a container, filtration, and spawning materials.

婚配系的常见问题

Q.Does the tri-color pattern change as the fish grows?

A.Yes, patterns that appear faint in fry often sharpen as the fish reaches adulthood. Conversely, red tones may fade in older fish. Growing them out for six months to a year lets you appreciate the full, mature coloration.

Q.Are they better suited for outdoor biotopes or indoor tanks?

A.Both work well. Outdoor biotopes allow sunlight to encourage phytoplankton growth, which can enhance coloration naturally. Indoor tanks with LED lighting and a black background showcase the pattern beautifully.
