A refreshing medaka with yamabuki (bright yellow) body color. Brighter than Youkihi, closer to lemon shade.
Yamabuki medaka is an improved variety featuring vivid yellow body color reminiscent of Yamabuki (Japanese kerria rose) flowers. Unlike Youkihi's reddish vermilion, it displays lemon-yellow to vivid yellow coloration that brightens any tank. A longstanding representative of yellow-spectrum medaka varieties. Light or white containers best showcase the yellow color. Fixation rate is relatively high compared to other color-enhanced varieties, reducing selection burden and making it easy to keep. Extremely hardy in 5–30°C, neutral to slightly alkaline water. Suitable for outdoor biotopes and indoor tanks alike. Easy to breed with regular spawning. Peaceful and community-friendly — a go-to yellow medaka for hobbyists of all levels.
