科: Cyprinidae
圆口铜鱼为鲤科鱼类，对同类温和，对小鱼不留情，原生分布于中国长江水系。高原河流的冷水性鲤科鱼，请按温带溪流鱼而非热带鱼对待。成体约 11.2–16.5 cm，幼鱼群游，成鱼成对或单养，适宜水温 18–26 °C。降温比喂食更重要。
From the waters of Yangtze basin, China comes Coreius guichenoti, a member of the family Cyprinidae. A cold, torrent-dwelling cyprinid of the plateau rivers — treat it like a temperate trout-stream fish, not a tropical. It uses the whole water column. Adults reach 11.2–16.5 cm. Juveniles shoal; adults keep to pairs or singles. Plan for chillers or a cool room, strong flow and excellent oxygen — heat kills where hunger cannot. Maintain 18–26 °C at pH 6.5–7.5. Undemanding once its core needs are met.
