over 150, see text Dermatocheir Durbin, 1909 Megalamphodus Eigenmann, 1915 Pseudopristella Géry, 1960 Hyphessobrycon is a genus of freshwater fish in the family Characidae.

The genus is distributed in the Neotropical realm from southern Mexico to Río de la Plata in Argentina.

These species are generally omnivorous, feeding predominantly on small crustaceans, insects, annelid worms, and zooplankton.

[2] The characteristic of extension of scales onto the caudal fin that differentiates this genus from Hemigrammus is not satisfactory, as it occurs in intermediate conditions.

Many Hyphessobrycon species are popular aquarium fish, and some, including H. flammeus, are bred in large numbers in captivity.
