種の概要

Discovered in 1932 on Baiyun Mountain near Guangzhou, the white cloud minnow is one of the most forgiving aquarium fish ever kept. It thrives in cool, unheated tanks, tolerates a wide chemistry range, and breeds readily among fine-leaved plants. Males flare their red fins in display — a splash of living color that asks almost nothing in return.
