Hydrolycus tatauaia is a species of dogtooth characin found in the Amazon, Orinoco and Essequibo basins in tropical South America.[1][2] Adults mainly occur in deep and/or fast-flowing rivers.[3] It is migratory, moving upstream to breed in November–April.[4]
Like other Hydrolycus species, H. tatauaia has long pointed canine teeth that are used to spear their prey, generelly smaller fish.[4] The body and head are silvery, and there is a vertically elongated dark spot behind the opercle. The tail is reddish to orange.[2][4][5] The species name tatauaia is of Tupi origin and means "fire tail".[2][6] It reaches up to 59 cm (1.94 ft) in total length and 2.7 kg (6.0 lb) in weight.[1]
This predatory fish occasionally makes its way into the aquarium trade, but it requires a very large tank.[4]
