Nandus is a genus of Asian leaffishes native to southern and southeastern Asia. [2]
The currently recognized species in this genus are: [2]
Clarias is a genus of catfishes of the family Clariidae, the airbreathing catfishes. The name is derived from the Greek chlaros, which means lively, in reference to the ability of the fish to live for a long time out of water.
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.
Leaffishes are small fishes of the family Polycentridae. According to FishBase, it only includes the genera Monocirrhus and Polycentrus from fresh and brackish water in tropical South America. Although included in the Asian leaffish family Nandidae by FishBase, most recent authorities place the African Afronandus and Polycentropsis in Polycentridae. Polycentridae were formerly placed in the order Cichliformes but are now regarded as being incertae sedis in the subseries Ovalentaria in the clade Percomorpha.
Kryptopterus is a genus of catfishes belonging to the family Siluridae. They are found in freshwater throughout Southeast Asia. The scientific name comes from Ancient Greek kryptós + ptéryx. It refers to the reduced or even entirely absent dorsal fin of these catfishes.
Batasio is a genus of catfish of the family Bagridae. These small fish are found in fast-flowing hillstreams throughout South and mainland Southeast Asia.
Bagrichthys is a genus of bagrid catfishes.
Hyalobagrus is a genus of bagrid catfishes found in Southeast Asia.
Nanobagrus is a genus of bagrid catfishes found in Southeast Asia. All species are quite small fish.
Erethistoides is a genus of South Asian river catfishes.
Exostoma is a genus of sisorid catfishes native to Asia. These species are distributed in the Brahmaputra drainage of northeast India, and east and south to the Salween drainages in Burma. E. berdmorei is found in the Sittang and Salween drainages in Burma. E. labiatum is known from the Brahmaputra drainage in northeast India, but has also been recorded in the Salween drainage in Burma, the Ayeyarwady drainage in China, and the Brahmaputra drainage in Tibet and Burma. E. stuarti is from the Ayeyarwady River of Burma and India; however, it has not been collected since its original discovery. E. labiatum is found in mountain rapids.
Ompok is a genus of fish in the family Siluridae found in lakes and large rivers throughout South and Southeast Asia.
the African leaffish is a species of African leaffish native to fresh waters of western Africa. Although placed in the family Nandidae by FishBase and by the 5th Edition of Fishes of the World many recent authorities place Polycentropsis in Polycentridae.
Luciocephalus is a genus of gouramies native to Southeast Asia. Both are extremely specialized niche predators native to parts of Thailand, Malaysia, Indonesia and Brunei Darussalam; in addition, both species - like a number of other osphronemid genera - are paternal mouthbrooders.
Polycentrus is a genus of small fish belonging to the family Polycentridae. They are found in fresh and brackish water in northern South America and Trinidad.
Nandus nandus, commonly known as the Gangetic leaffish, is a species of Asian leaffish native to South Asia and Indochina. They are common in slow-moving or stagnant bodies of water, including ponds, lakes, ditches, and flooded fields. Other common names of the species include mottled nandus and mud perch. They are commercially important and are highly prized as food fish. They are also caught for the aquarium trade.
Pristolepis grootii, commonly known as the Indonesian leaffish, is a fish native to streams of the Indonesian islands of Sumatra, Bangka, Belitung and Borneo, and Thailand. It is part of the first Western Indonesian and Sulawesi Freshwater fish species recorded by December 31, 1991 along with another 963 species. Further research lead to the discovery of other 79 fish species in the area. By May 31st, 1996 deletions and additions were made revealing a grand total of 1032 known fish species in the area. The specific name honours the Dutch naturalist and ethnographer Cornelis de Groot van Embden (1817-1896).
Pristolepis fasciatus, commonly known as the Malayan leaffish, is a fish in the family Pristolepididae. It lives in the Mekong and Chao Phraya basins in Thailand, Cambodia, Vietnam, Myanmar, the Malay Peninsula, Sumatra, and Borneo, possibly also in southern India and China.
Nandus oxyrhynchus is a species of ray-finned fish from the family Nandidae. It is native to the Mekong River Basin, Chao Phraya River Basin, and Mae Klong River Basin. It occurs in slow flowing and still waters in streams, rivers, pond and lakes. It is a carnivorous fish preying on other fishes and larger invertebrates.
Pristolepis is a genus of fish in the family Pristolepididae sometimes classified in the order Anabantiformes native to freshwater habitats in Southeast Asia and India's Western Ghats. 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".
