Description

The red-tailed freshwater barracuda is a slender predator of the family Acestrorhynchidae reaching about 30 cm. The streamlined, silvery body has a pointed head with a mouth full of sharp, needle-like teeth, an adipose fin (as in many characins) and a conspicuous black spot on the tail base with a red-coloured tail fin. Its build makes it resemble a small freshwater barracuda. The species comes from the Amazon and Orinoco basins and the Guianas of northern South America and lives in open water of rivers, lakes and floodplains. As a fast pursuit predator it feeds mainly on smaller fish. In the rainy season it spawns. For its size and behaviour it occasionally appears in the larger community aquarium.
