The family Danionidae currently contains about 40 genera and 367 species. The best known two genera are Rasbora and Danio.
Research and changes
In the last few decades, regular research has been done on the species within this family. Changes have therefore been made regularly. Some species have been assigned a new genus. Other species have been classified as synonyms, or even elevated from synonyms to their own species. It is therefore expected that many more changes will be made in the coming years.
