Taxonomy
Many species that were formerly within the Danio genus, such as the giant danio, have now been reclassified as Devario. In addition, Devario acuticephala, Devario shanensis and Devario sondhii were also regarded at one time as being in the now junior synonym genus Brachydanio.
The Khanka spiny bitterling (Acanthorhodeus chankaensis) and the Russian bitterling (Acheilognathus asmussii) were previously classified as Devario, but now are placed in a completely different subfamily, the Acheilognathinae (bitterlings).
