Hydrolycus armatus is a species of dogtooth characin found in freshwater of tropical South America.[1] It is sometimes known as the payara,[2][3][4] a name it shares with the related H. scomberoides.
This predatory fish occasionally makes its way into the aquarium trade, but it requires a very large tank.[2] In its native range it is considered a major gamefish.[4]
Distribution and habitat
This species of fish is found in the Amazon, Orinoco and Essequibo basins in tropical South America.[1][5] They are found in several different freshwater habitats, but often in fast-flowing water.[4]
Description
A typically reported maximum size of this fish is 8.5 kg (19 lb) in weight and 89 cm (2.92 ft) in length,[1] but records from Venezuela show specimens up to 95 cm (3.12 ft).[3] It can weigh up to almost 18 kg (40 lb).[4] It has frequently been confused with the generally smaller H. scomberoides.[2][5] Like other dogtooth characins, H. armatus has very long pointed canine teeth that can surpass 5 cm (2.0 in) in length in large individuals.[3] These are used for spearing their prey, usually other fish.[6]
