Description

The silver dollar tetra is a deep, disc-shaped characin of the family Characidae (true tetras) reaching about 9 cm. The strongly compressed, mirror-silver body resembles a small silver dollar and bears an adipose fin (as in many characins) and a dark shoulder spot. The species comes from the fresh water of northern and central South America and lives in schools in slow, densely vegetated water of rivers and creeks. As an omnivore it eats insects, plant matter, zooplankton and detritus, taken in the water column and at the surface. In the rainy season it spawns among the water plants. Through its great numbers it is an important prey fish for larger species and occasionally appears in the aquarium hobby.
