Biting Tetra
Acestrorhynchidae is a family of freshwater fish in the order Characiformes, found in South America. Members of this family are known as freshwater barracudas (not to be confused with the unrelated true barracudas of the Sphyraenidae) and biting tetras. Until recently, this family contained only the genus '' Acestrorhynchus''.
