who is the piau-do-chimoré
The Chimoré piau is a freshwater anostomid of the headstander family (piaus and aracus), reaching 10.5 cm, a small size for the group. It lives between the bottom and the midwater, in rivers of Bolivia, such as the Chimoré in Cochabamba, and of Ecuador. Pairs breed in areas with very dense plants. Like other piaus, it is omnivorous. It has commercial fishing. Because of its small size, it is hardly ever caught on the line in recreational fishing.
