Puntius is a genus of small freshwater fish in the family Cyprinidae native to South Asia and Mainland Southeast Asia, as well as Taiwan.
Channa is a genus of predatory fish in the family Channidae, commonly known as snakeheads, native to freshwater habitats in Asia. This genus contains about 50 scientifically described species. The genus has a wide natural distribution extending from Iraq in the west, to Indonesia and China in the east, and parts of Siberia in the Far East. A particularly high richness of species exists in Myanmar (Burma) and northeastern India, and many Channa species live nowhere else. In contrast, a few widespread species have been introduced to several regions outside their natural range, where they often become invasive. The large and medium-sized Channa species are among the most common staple food fish in several Asian countries, and they are extensively cultured. Apart from their importance as a food fish, snakeheads are consumed in some regions as a traditional medicine for wound healing and reducing postoperative pain and discomfort, and collected for the international aquarium pet trade.
Rasbora is a genus of fish in the family Cyprinidae. They are native to freshwater habitats in South and Southeast Asia, as well as southeast China. A single species, R. gerlachi, is only known from an old specimen that reputedly originated from Africa (Cameroon), but this locality is considered doubtful. They are small, up to 17 cm (6.7 in) long, although most species do not surpass 10 cm (4 in) and many have a dark horizontal stripe.
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.
Leaf fish or Leaffish may refer to:
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.
Glyptothorax is a genus of catfishes order Siluriformes of the family Sisoridae. It is the most species-rich and widely distributed genus in the family with new species being discovered on a regular basis. These species are distributed in the Black Sea basin, northern Turkey, south and east to the Yangtze River drainage in China and south throughout Indo-China to Java, Indonesia. They are found in Asia Minor and southwards to Southeast Asia. The genus is very diverse in the Indian subcontinent. Southeast Asian species tend to have restricted distributions.
Macrognathus is a genus of eel-like fish of the family Mastacembelidae of the order Synbranchiformes.
Mystus is a genus of fish in the family Bagridae native to Asia. Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.
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.
The fourspine leaffish, is a species of in the Nandidae native to rivers and streams in Ivory Coast and Ghana. Although placed in the family Nandidae by FishBase, most recent authorities place Afronandus in Polycentridae. The specific name honours the collector of the type, Leo Sheljuzhko (1890–1969), a Ukrainian-German entomologist who sent the type to Meinken.
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.
The Anabantiformes, collectively known as Labyrinth fish. are an order of air-breathing freshwater ray-finned fish with two suborders, five families and having at least 207 species. In addition, some authorities expand the order to include the suborder Nandoidei, which includes three families - the Nandidae, Badidae and Pristolepididae - that appear to be closely related to the Anabantiformes. The order, and these three related families, are part of a monophyletic clade which is a sister clade to the Ovalentaria, the other orders in the clade being Synbranchiformes, Carangiformes, Istiophoriformes and Pleuronectiformes. This clade is sometimes referred to as the Carangaria but is left unnamed and unranked in Fishes of the World. This group of fish are found in Asia and Africa, with some species introduced in United States of America.
Channa royi, the Andaman emerald snakehead, is a species of snakehead fish endemic to the Andaman and Nicobar Islands of India. This dwarf snakehead is distinct from other snakehead species due to its differing coloration, number of vertebrae, and teeth, most notably its greenish-gray dorsum. It was only scientifically described in 2018 and its closest relative is the Burmese snakehead, and a review in 2019 argued that the two are synonyms.
Aenigmachanna is a genus of ray-finned fish in the order Ananbantiformes. It is the only genus in the family Aenigmachannidae, or dragon snakeheads. It contains two species, both of which are largely restricted to subterranean habitats in southwestern India, namely in the Western Ghats foothills in the state of Kerala.
Trichopodus poptae is a species of ray-finned fish in the subfamily Luciocephalinae, part of the gourami family Osphronemidae. It is distinguished from its congeners by the faint, almost indiscernible patterning on the body apart from the black blotch at the base of the tail. This species is endemic to Kalimantan, the Indonesian part of the island of Borneo.
The licorice gourami is a species of freshwater ray-finned fish from the subfamily Macropodusinae, part of the family Osphronemidae, the gouramis. It is endemic to Bangka in Indonesia where it is found in the slow, flowing streams with black waters associated with peat swamp forests. This species was formally described by the Dutch ichthyologist Pieter Bleeker as Osphromenus deissneri in 1859 with the type locality given as Sungai Baturussa basin at 8 kilometres from Pudingbesar on the road to Kampong Simpan, Bangka. It is the type species of the genus Parosphromenus. The specific name honours F. H. Deissner, a military health officer, who sent a collection of specimens of fishes from Bangka to Bleeker which included the type of this species.
The Malabar Leaffish is a species of freshwater fish in the family Pristolepididae. It lives in the Western Ghats in India.
