科: Cyprinidae
日本鳑鲏为鲤科鱼类，温和的群游鱼，不宜与大型鱼同缸，原生分布于朝鲜半岛（水原）。繁殖依赖活体淡水河蚌，因此细沙底床与稳定水质比造景更重要。成体约 4.9–7.2 cm，群游性，建议 8 尾以上，适宜水温 18–25 °C。饲养不难，难在稳定。
From the waters of Suwon, Korea comes Rhodeus suigensis, a member of the family Cyprinidae. Like its relatives it depends on living freshwater mussels for breeding, so a fine-sand bed and settled water matter more than décor. It lives on the bottom. Adults reach 4.9–7.2 cm. Shoaling; keep at least 8 together. Offer small foods in calm corners and keep the water stable — this fish forgives little else in the way of sloppiness. Maintain 18–25 °C at pH 6.5–7.5. A solid choice for a well-planned community tank.
