Metynnis
Genus of fishes
From Wikipedia, the free encyclopedia
Metynnis also commonly known as the silver dollar is a genus of freshwater ray-finned fishes belonging to the family Serrasalmidae, which includes the pacus, piranhas and related fishes. The fishes in this genus are found in tropical and subtropical South America.[2] They are herbivorous or omnivorous, and inhabit a wide range of freshwater habitats, ranging from rivers and streams (both fast- and slow-flowing), to floodplains, flooded forests, lakes, pools and reservoirs.[3] They generally reach 8–15 cm (3–6 in) in standard length,[3] although a few species may reach up to 18 cm (7 in).[2] The genus contains many of the species known as silver dollars in the aquarium trade.
