Microrasbora is a genus of small fishes. The generic name means "small Rasbora", however these are more closely related to the danios than rasboras. [1] They inhabit freshwater in Myanmar and Yunnan, China. [2]

Taxonomy

Microrasbora, until recently, included a number of described species. Microrasbora erythromicron was first shown to be a member of the genus Danio in 1999. [3] This move has been confirmed by numerous studies. [1] [4] Three other species, M. gatesi , M. kubotai , and M. nana were moved to a new genus, Microdevario , [4] leaving Microrasbora rubescens as the only confirmed species in the genus. However, Fang et al. did not comment on the placement of Microrasbora microphthalma.

Species

Two described species are currently included in this genus: [2]

<span class="mw-page-title-main">Cyprinidae</span> Family of freshwater fish

Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 3,000 species; only 1,270 of these remain extant, divided into about 200 valid genera. Cyprinids range from about 12 mm (0.5 in) in size to the 3 m (9.8 ft) giant barb. By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word kyprînos.

<span class="mw-page-title-main">Cypriniformes</span> Order of fishes

Cypriniformes is an order of ray-finned fish, which includes many families and genera of cyprinid fish, such as barbs, gobies, loaches, botias, and minnows. Cypriniformes is an “order-within-an-order”, placed under the superorder Ostariophysi—which is also made up of cyprinid, ostariophysin fishes. The order contains 11-12 families, over 400 genera, and more than 4,250 named species; new species are regularly described, and new genera are recognized frequently. Cyprinids are most diverse in South and Southeast Asia, but are entirely absent from Australia and South America. At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo.

<i>Devario</i> Genus of fishes

Devario is a genus of fish in the family Cyprinidae native to the rivers and streams of South and Southeast Asia. These fishes have short barbels and many species having vertical or horizontal stripes. These species consume various small, aquatic insects, crustaceans and worms, as well as, in the case of fry, plankton.

<i>Rasbora</i> Genus of fishes

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.

<i>Danio</i> Genus of fishes

Danio is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia, commonly kept in aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbels. Species of this genus consume various small aquatic insects, crustaceans and worms.

<i>Microdevario kubotai</i> Species of fish

Microdevario kubotai is a species of cyprinid found in southeast Asian rivers and streams. It belongs to the genus Microdevario, which contains small danionins. The type locality is in Ranong Province, Peninsular Thailand. It is also known from the adjacent Phang Nga Province and the Ataran basin in Myanmar. It likely occurs elsewhere in the region and an introduced population exists in the Songgaria River. It reaches up to 1.9 cm (0.75 in) in length,the maximum length can reach 2.5 cm (0.98 in).

<i>Danio margaritatus</i> Species of fish

Danio margaritatus, the celestial pearl danio, often referred to in the aquarium trade as galaxy rasbora or Microrasbora sp. 'Galaxy', is a small cyprinid from Myanmar and Northern Thailand. It has so far been found only in a very small area near Hopong east of Inle Lake, at an elevation of over 1,000 m (3,400 ft). Its habitat is part of the Salween basin, namely the Nam Lang and Nam Pawn Rivers. Discovered in 2006, the species quickly appeared in the aquarium trade, where its small size and bright colours made it an instant hit.

<i>Schizothorax</i> Genus of fishes

Schizothorax is a genus of cyprinid fish found in southern and western China, through northern South Asia (Himalaya) and Central Asia, to Iran, with a single species, S. prophylax, in Turkey. They are primarily found in highland rivers, streams and lakes, although a few species occur in lower-lying locations, like Lake Balkhash and lakes of the Sistan Basin. Their scientific name means "cloven-breast", from Ancient Greek schízeïn (σχίζειν) 'to cleave' and thórax (θώραξ) 'breast-plate'. The western species are typically referred to as marinkas from their Russian name marinka (маринка), while the eastern species are usually called snowtrout. Although they do resemble trouts in habitus this is merely due to convergent evolution and they are by no means closely related apart from both being Teleostei: Cyprinids are in the teleost superorder Ostariophysi, while trouts are in the superorder Protacanthopterygii. Their ancestors must thus have diverged as early as the Triassic, more than 200 million years ago.

<i>Capoeta</i> Genus of fishes

Capoeta, also known as scrapers, is a genus of fish in the family Cyprinidae found in Western Asia. The distribution extends from Turkey to the Levant, to Transcaucasia, Iraq, Turkmenistan, in Armenia, particularly in lake Sevan and northern Afghanistan. This genus is most closely related to Luciobarbus and in itself is divided into three morphologically, biogeographically and genetically distinct groups or clades: the Mesopotamian clade, the Anatolian-Iranian clade and the Aralo-Caspian clade.

<i>Garra</i> Genus of fishes

Garra is a genus of fish in the family Cyprinidae. These fish are one example of the "log suckers", sucker-mouthed barbs and other cyprinids commonly kept in aquaria to keep down algae. The doctor fish of Anatolia and the Middle East belongs in this genus. The majority of the more than 160 species of garras are native to Asia, but about one-fifth of the species are from Africa.

<i>Danio erythromicron</i> Species of fish

Danio erythromicron, often known as emerald dwarf danio and emerald dwarf rasbora, is a species of cyprinid fish which is endemic to Inle Lake in Myanmar.

<span class="mw-page-title-main">Labeoninae</span> Subfamily of fishes

Labeoninae is a doubtfully distinct subfamily of ray-finned fishes in the family Cyprinidae of order Cypriniformes. They inhabit fresh water and the largest species richness is in the region around southern China, but there are also species elsewhere in Asia, and some members of Garra and Labeo are from Africa. They are a generally very apomorphic group, perhaps the most "advanced" of the Cyprinidae. A common name for these fishes is labeonins or labeoins.

<i>Microdevario</i> Genus of fishes

Microdevario is a small genus of danionin cyprinids. It was recently described to include species previously in the genus Microrasbora. These small freshwater fish are native to Burma (Myanmar) and adjacent parts of Thailand, and reach up to 1.5–2.3 cm (0.6–0.9 in) in length depending on the exact species involved.

<span class="mw-page-title-main">Least rasbora</span> Species of fish

The least rasbora or exclamation point rasbora is a species of ray-finned fish in the genus Boraras, native to freshwater habitats in mainland southeast Asia. This species is very small, ranging from 12 to 16 mm.

<span class="mw-page-title-main">Danionin</span> Subfamily of fishes

The danionins are a group of small, minnow-type fish belonging to the family Cyprinidae. Species of this group are in the genera clades danio and devario, based on the latest phylo-genetic research by Fang et al in 2009. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. Fishes of the danio clade tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels. Species within the devario clade tend to have vertical or horizontal bars, and short, rudimentary barbels, if present at all. All danionins are egg scatterers, and breed in the rainy season in the wild. They are carnivores, living on insects and small crustaceans.

Microdevario gatesi is a species of cyprinid found in southeast Asian rivers and streams. It belongs to the genus Microdevario, which contains small danionins. It is endemic to the lower Irrawaddy River drainage in south central Myanmar. It reaches up to 2.3 cm (0.91 in) in length.

Microdevario nana is a species of cyprinid found endemic to Myanmar. It belongs to the genus Microdevario, which contains small danionins. It reaches up to 1.9 cm (0.75 in) in length.

<span class="mw-page-title-main">Red dwarf rasbora</span> Species of fish

Red dwarf rasbora is a species of cyprinid found endemic to Lake Inle in Shan State in Myanmar. It belongs to the genus Microrasbora, which contains two small species of danionins.

Microrasbora microphthalma is a species of cyprinid that is endemic to small hill streams in Yunnan, China. It belongs to the genus Microrasbora, which contains small danionins. It reaches up to 2.6 cm (1.0 in) in standard length.
