Nandus

Nandus, the Asian leaffishes, is a genus of small freshwater ray-finned fishes native to southern and southeastern Asia. It is the only member of the family Nandidae, which is classified in the order Anabantiformes and closely related to the Badidae and Pristolepididae.

Fishes of the World considered this family and its relatives to be of uncertain taxonomic placement, but more recent taxonomic studies have reaffirmed its anabantiform affinities. Until recently, this family also contained Afronandus and Polycentropsis of tropical West and Middle Africa. However, genetic studies suggest that these the two African genera actually belong to the Cichliform South American leaffish family Polycentridae, which is only distantly related to Nandus (the "true" Nandidae). Nandus remains closely related to the other Anabantiform leafish family, the Pristolepididae, or Asian Leaffishes.
