Rasbora is a genus of fish in the family Cyprinidae. [1] They are native to freshwater habitats in South and Southeast Asia, as well as southeast China. [1] A single species, R. gerlachi, is only known from an old specimen that reputedly originated from Africa (Cameroon), but this locality is considered doubtful. [2] 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. [1]
Several species are regularly kept in aquariums. As a common English name, "rasbora" is used for many species in the genus Rasbora, as well as several species in genera Brevibora , Boraras , Megarasbora , Metzia , Microdevario , Microrasbora , Rasboroides , Rasbosoma , Sawbwa , Trigonopoma and Trigonostigma . [3] Some of these related genera were included in the genus Rasbora in the past. In a 2007 analysis, Rasbora was found to not be a monophyletic assemblage. However Boraras and Trigonostigma were determined to be monophyletic. [4]
According to FishBase, 84 recognized species are in this genus. [1] This differs to some extent from the treatment by Catalog of Fishes, where some of these are regarded as junior synonyms and a few others (not listed below) are recognized as valid species. [5]
Puntius is a genus of small freshwater fish in the family Cyprinidae native to South Asia and Mainland Southeast Asia, as well as Taiwan.
Pangio is a genus of small Asian freshwater fish in the true loach family Cobitidae. In earlier taxonomic schemes it was known as Acanthophthalmus. The "kuhli loach" is well-known in the aquarium trade and commonly identified as P. kuhlii, but most individuals actually appear to be P. semicincta.
Sundadanio is a genus of cyprinid fishes from freshwater habitats, typically peat swamps and blackwater streams, in Borneo and Sumatra in southeast Asia. At up to 2.3 cm (0.91 in) in standard length they are very small, but still larger than their close relatives Paedocypris. Species of the two genera are often found together.
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.
Barbonymus is a ray-finned fish genus in the family Cyprinidae, containing some barb species. The genus was only established in 1999, with the tinfoil barb as type species; thus, these fish are sometimes collectively called tinfoils. The new genus was established in recognition of the fact that some large Asian "barbs", formerly rather indiscriminately lumped in Barbus, Barbodes and Puntius, form a distinct evolutionary lineage.
Barbodes is a genus of small to medium-sized cyprinid fish native to tropical Asia. The majority of the species are from Southeast Asia. Many species are threatened and some from the Philippines are already extinct. A survey carried out in 1992 only found three of the endemic Barbodes species, and only two were found in 2008. Several members of this genus were formerly included in Puntius.
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.
Onychostoma is a genus of cyprinid fish found in eastern Asia.
Rasbora dandia is a species of ray-finned fish in the genus Rasbora from India, Pakistan and Sri Lanka.
Rasbora cephalotaenia is a species of ray-finned fish in the genus Rasbora. It is found on the Malay Peninsula and Indonesia.
The Gobionellinae are a subfamily of fish which was formerly classified in the family Gobiidae, the gobies, but the 5th Edition of Fishes of the World classifies the subfamily as part of the family Oxudercidae. Members of Gobionellinae mostly inhabit estuarine and freshwater habitats; the main exception is the genus Gnatholepis, which live with corals in marine environments. The subfamily is distributed in tropical and temperate regions around the world with the exception of the northeastern Atlantic Ocean, the Mediterranean Sea, and the Ponto-Caspian region. It includes around 370 species and 55 genera: Wikipedia articles about genera list about 389 species.
Crossocheilus, also known as the fringe barbs, flying foxes, or "algae eaters", is a genus of fish in the family Cyprinidae. It is distributed in China, India, Indonesia, Malaysia and Thailand in Asia. These fish occur in several types of habitat, often fast-flowing rivers with rocky bottoms.
Osteochilus is a genus of cyprinid fishes mainly found in Southeast Asia with a few extending into adjacent parts of China. Additionally, two species are endemic to the Western Ghats in India.
Rohan David Pethiyagoda is a Sri Lankan biodiversity scientist, amphibian and freshwater-fish taxonomist, author, conservationist and public-policy advocate.
Dawkinsia is a genus of cyprinid fishes from freshwater in South India and Sri Lanka. It was split off from genus Puntius in 2012.
Pethia is a genus of small freshwater fish in the family Cyprinidae native to South Asia, East Asia and Mainland Southeast Asia. Some species are commonly seen in the aquarium trade. The name Pethia is derived from the Sinhalese "pethia", a generic word used to describe any of several small species of cyprinid fishes. Most members of this genus were included in Puntius, until it was revised in 2012.
Haludaria is a genus of cyprinids native to freshwater habitats in the Western Ghats of India. Originally the genus was named DravidiaPethiyagoda, Meegaskumbura & Maduwage, 2012 which is preoccupied by the dipteran genus DravidiaLehrer, 2010.
Laubuka is a genus of cyprinid fish found in South and Southeast Asia.
Barbodes xouthos is a species of freshwater ray-finned fish from the carp and minnow family Cyprinidae. It has only been recorded from Brunei on the island of Borneo. It has an unusual pattern on its body consisting of a plain brown body with faint reticulations.
