Nandidae, the leaffish, are a family of small freshwater fishes which some authorities classify in the order Anabantiformes, but which the 5th edition of Fishes of the World classifies the family and the related Badidae and Pristolepididae outside that order as "sister-taxa". Fishes of the World classified these families and the Anabantiformes alongside Synbranchiformes, Carangiformes, Istiophoriformes and Pleuronectiformes in a monophyletic clade which is a sister taxon to the Ovalentaria but to which the authors do not assign a rank or a name. According to FishBase, the family includes three genera: Nandus of South and Southeast Asia with several species, and the monotypic Afronandus and Polycentropsis of tropical West and Middle Africa. Most recent authorities place the two African genera in the South American leaffish family, Polycentridae, which is only distantly related to Nandus. Another Asian family, Pristolepididae, share the common name leaffish and appear to be more closely related.
Trichogaster is a genus of gouramis native to South Asia from Pakistan to Myanmar. It is the only genus in the monotypic subfamily Trichogastrinae as set out in the 5th Edition of Fishes of the World, although that book states that there are two genera, the other being Colisa which is treated as a synonym of Trichogaster by Fishbase and the Catalog of Fishes. Fishbase also places the genus in the Luciocephalinae. Species of this genus are very popular in the aquarium trade.

Betta chini is a species of gourami endemic to the island Borneo where it is only known from the Malaysian state of Sabah. It inhabits very shallow waters of peat swamps.

Badis badis, also known as the blue perch or blue badis, is a small species of Asian freshwater fish in the family Badidae of the order Anabantiformes. It is found in ponds, rivers, ditches and swamps in northern India, eastern Pakistan, Bangladesh, Bhutan and Nepal, including the Ganges, Brahmaputra, Mahanadi and Indus basins. It is sometimes kept as an aquarium fish. It is a small, predatory fish that feeds on tiny invertebrates. Maximum total length is around 8 cm (3 in). It is sexually dimorphic, with males growing larger and being more colorful, especially when excited, compared to females. Adult males have blue fins and may display dark vertical bands on the flanks, while the smaller females display little color. Several similar relatives, now recognized as separate Badis species, have historically been confused with Badis badis. Historically the two genera that now make up the Badidae, Badis and Dario, were placed in the family Nandidae; this is no longer the case.
Betta enisae is a species of gourami endemic to the Kapuas River basin of Indonesia. It is an inhabitant of forest streams with slightly acidic waters, and can mostly be found in the shallows amongst the leaf litter. This species grows to a length of 5.9 cm (2.3 in).

This species grows to a length of 8.2 cm (3.2 in), and can be found in the aquarium trade.

Walter is honoured in the specific name of another species they discovered, Betta foerschi.
Betta tussyae is a species of gourami endemic to Malaysia where it is only known from Pahang. It is an inhabitant of peat swamps. This species grows to a length of 3.7 centimetres (1.5 in) SL. The specific name honours Tussy Nagy, the wife of the Austrian aquarist Peter Nagy, in 1979 this couple were the first fish collectors to import this species into Europe.

This species grows to a length of 7 cm (2.8 in). It can be found in the aquarium trade. The specific name of this fish honours the German physician and aquarist Walter Foersch (1932-1993), who collected the type with his wife Edith Korthaus. Edith is honoured in the specific name of another species they discovered, Betta edithae.

This genus is the only member of its family, a family which, with the families Nandidae and Polycentridae is a group of taxa which are sisters to the Anabantiformes and form part of an unnamed and unranked clade within the series Ovalentaria, closest to the Carangiformes. These three families share the common name "leaffish".
