 More recent revision has moved many former members of the family into their own related but distinct families – the pencilfishes of the genus "Nannostomus" are a typical example, having now been moved into the Lebiasinidae, the assorted predatory species belonging to "Hoplias" and "Hoplerythrinus" have now been moved into the Erythrinidae, and the sabre-toothed fishes of the genus "Hydrolycus" have been moved into the Cynodontidae.The former subfamily Alestiinae was promoted to family level (Alestiidae) and the subfamilies Crenuchinae and Characidiinae were moved to the family Crenuchidae.Other fish families that were formerly classified as members of the Characidae, but which were moved into separate families of their own during recent taxonomic revisions (after 1994) include Acestrorhynchidae, Anostomidae, Chilodontidae, Citharinidae, Ctenoluciidae, Curimatidae, Distichodontidae, Gasteropelecidae, Hemiodontidae, Hepsetidae, Parodontidae, Prochilodontidae, Serrasalmidae, and Triporthidae.
