棘背鳑鲏 (Rhodeus spinalis)

科: Cyprinidae

棘背鳑鲏为鲤科鱼类,性情平和,需避开爱咬鳍的鱼,原生分布于中国各水系。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 7.5–11 cm,群体越大状态越放松,适宜水温 18–25 °C。饲养不难,难在稳定。

物种概述

Cyprinidae species Rhodeus spinalis comes from China. Like its relatives it depends on living freshwater mussels for breeding, so a fine-sand bed and settled water matter more than décor. It uses the whole water column. Adults reach 7.5–11 cm. Sociable; a larger group spreads any squabbles. 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. Best suited to a keeper who can match its natural water.
