Description

The bigscale tetra is a silvery characin of the family Characidae (true tetras) reaching about 10 cm. The laterally compressed body has conspicuously large, shiny scales, an adipose fin (as in many characins) and a dark spot on the tail base. The species comes from the Amazon basin in South America and lives in schools in clear streams and rivers with vegetated banks. As an omnivore it eats insects, zooplankton, algae and plant matter, 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.
