The black ruby barb or purplehead barb is a tropical cyprinid fish endemic to Sri Lanka, where it occurs in forested streams from the Kelani basin to the Nilwala basin. They are found in streams on hills around 1000 ft in elevation. The brightly colored population introduced to Mahaweli at Ginigathena, Sri Lanka, is said to have diminished in number due to the aquarium export trade.
Puntius is a genus of small freshwater fish in the family Cyprinidae native to South Asia and Mainland Southeast Asia, as well as Taiwan.
The ticto barb or twospot barb is a species of subtropical freshwater fish belonging to the family Cyprinidae. It is a native of the upper Mekong, Salwen, Irrawaddy, Meklong and upper Charo Phraya basins in the countries of Nepal, India, Pakistan, Myanmar, Bangladesh, Thailand, and Sri Lanka. It has frequently been confused with the Odessa barb in the aquarium trade, but in that species the male is reddish-orange.
The Malabar danio is a tropical fish belonging to the minnow family (Cyprinidae). Originating in Sri Lanka and the west coast of India, the fish has been circulated throughout the world through the aquarium fish trade. It grows to a maximum length of 6 in (15 cm) rarely exceeds 4 in (10 cm) in a home aquarium.
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.
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.
The bandula barb is a species of cyprinid endemic to Sri Lanka where it is only known from near Galapitamada in the Warakapola Divisional Secretariat. As this critically endangered species only was known from a single unprotected site where the population consists of an estimated 1,000 individuals, a second "insurance population" was established in 2014 by a team of IUCN scientists in cooperation with Sri Lanka's Forest Department, the Department of Wildlife Conservation and local communities.
Rasboroides vaterifloris, known as the pearly rasbora, vateria flower rasbora or fire rasbora, is a species of freshwater cyprinid fish endemic to Sri Lanka. It can be found in the shallow waters of shaded, slow-flowing clear streams with a silt substrate. It also prefers areas with plentiful leaf debris. Its diet consists of detritus and terrestrial insects. This species can reach a length of 4 centimetres (1.6 in) TL. It can also be found in the aquarium trade.
Pethia cumingii, known as the Cuming's barb or the two spot barb, is a species of cyprinid fish endemic to Sri Lanka.
Labeo dussumieri is fish in genus Labeo known to occur in west-flowing rivers of the Western Ghats. Earlier Sri Lankan population was considered as the same species as L. dussumieri, recent phylogenetic and physiological differences suggest that Sri Lankan population is a distinct species, Labeo heladiva..
Pethia reval, the red-finned barb, is a species of cyprinid fish endemic to Sri Lanka. This species can reach a length of 3.4 centimetres (1.3 in) SL.
The horadandia, green carplet, or glowlight carplet, is a species of very small cyprinid fish that is found in slow-moving or still fresh and brackish water habitats in western Sri Lanka. Earlier thought to be a monotypic genus with the single species found in both Sri Lanka and India, an analysis published in 2013 showed that the Indian population should be recognized as a separate species, Horadandia brittani.
Rasboroides is a genus of small cyprinid fishes endemic to Sri Lanka. They are found in small, slow-flowing and shaded streams in the southwestern part of the island. They are essentially restricted to lowlands, although one introduced population occurs at an altitude of 980 m (3,220 ft). They are calm, social and attractively colored fish that sometimes are kept in aquariums.

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.
Rasboroides pallidus is a species of freshwater cyprinid fish endemic to southwestern Sri Lanka. It is only known from shallow, slow-flowing streams in the basins of the Kalu River, Bentara River, Gin River, Polathu-Modera River and Nilwala River. It has been introduced to the Mahaweli and Walawe River basins, and is overall less threatened than the related R. vaterifloris.
Rasboroides rohani, is a species of freshwater cyprinid fish endemic to Sri Lanka where only known from shallow, slow-flowing, shady streams near Suriyakanda in the Walawe River basin. It was scientifically described in 2013, but a comprehensive review in 2018 based on morphometry, meristics and mtDNA disputed its validity, showing that it is a junior synonym of R. pallidus. The occurrence of R. pallidus in the Walawe River basin is not natural, but the result of translocations.
Lepidocephalichthys thermalis, known as the common spiny loach or the spotted loach, is a freshwater fish species found in India and Sri Lanka.
Horadandia brittani is a species of very small cyprinid fish that is endemic to coastal floodplains in South India. Originally described as a subspecies of H. atukorali, it was elevated to species level in 2013. It can grow to 2 cm (0.79 in) standard length.
