Description
The yellow flag tetra is a tiny South American characin of the family Characidae from the north of the continent, including the Guianas. The species grows to only about 2 cm - less than 3 cm - making it one of the smallest tetras. It has a slender, partly translucent body with a yellowish to reddish tinge. It lives in schools in quiet, often dark-stained forest brooks and creeks. As a small omnivore it feeds on small zooplankton, micro-invertebrates and plant matter. Owing to its extremely small size it is prey for larger fishes and is harmless to humans.
