Cyprinidae species Rhodeus amurensis comes from 中国. 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. 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.
