The twospot rasbora (Rasbora elegans) is a species of ray-finned fish in the genus Rasbora native to south east asia. It is one of the members of the Sumatrana group. [3]
Native to Peninsular Malaysia, Singapore and the Greater Sunda Islands (except Sulawesi and Java).
In Peninsular Malaysia, it is predominately found in Johor and Pahang, but also reported from the states of Negeri Sembilan, Perak and Kelantan.
It is a commonly found species in Singapore and can even be encountered outside the central catchment area of the island.
On Sumatra, the only record of the species is from the small island of Nias, although presumably it also occurs on the main island.
On Borneo, it is only confirm to occur in East Kalimantan and parts of the lower Kapuas River basin in West Kalimantan. It is not known if the species occur in Malaysian Borneo, Brunei Darussalam or north Kalimantan, Indonesia. [4]
It is easily distinguishable from others of its genus by lacking a dark stripe along the lateral line. Instead it possesses one rectangular spot below the dorsal fin origin and lateral line, and a second triangular spot at the caudal peduncle. The spots can be a dark black or faded, depending on the habitat and locality. In some cases a small marking can present above the anal fin. [4]
R. bunguranensis and R. spilotaenia used to be thought as subspecies of R. elegans. [3]
It can be found in clear forest streams and creaks with sandy or rocky bottom, spending most of its time near the surface searching for insects and other prey [5]
The Asian arowana comprises several phenotypic varieties of freshwater fish distributed geographically across Southeast Asia. While most consider the different varieties to belong to a single species, work by Pouyaud et al. (2003) differentiates these varieties into multiple species. They have several other common names, including Asian bonytongue, dragonfish, and a number of names specific to the different color varieties.
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 fire eel is a relatively large species of spiny eel. This omnivorous freshwater fish is native to in Southeast Asia but is also found in the aquarium trade. Although it has declined locally by overfishing, because of this trade it remains common overall.
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.
Acrochordonichthys is a genus of catfishes of the family Akysidae. It includes ten species.
The Odessa barb is a species of cyprinid fish known from Central Myanmar, where it is known to occur in an artificial pond above the Anisakan Falls and also from the lower Chindwin River. For many years it has been known to the aquarium hobby, where it has frequently been confused with the less colourful ticto barb), but it was only described scientifically in 2008.
The greater scissortail is a species of ray-finned fish in the genus Rasbora. It inhabits forest creeks in Malaysia, Indonesia and the lower Mekong basin.
The goldstripe rasbora is a species of ray-finned fish in the genus Rasbora. It is a benthopelagic freshwater fish found in Malaysia and Indonesia.
The yellow rasbora is a species of ray-finned fish in the genus Rasbora from Southeast Asia. It is a primarily freshwater fish originally from Java island in Indonesia. It is known as the Wader pari fish in the Indonesian language. In addition, it was a protein source for the local community during the old days.
Rasbora sarawakensis, also known as the blue line rasbora or Sarawak rasbora, is a species of ray-finned fish in the genus Rasbora which is endemic to the island of Borneo.
Leptobarbus hosii, the Sayan Barb also locally called as Piam and Temopong is a species of ray-finned fish in the genus Leptobarbus from freshwater habitats in northern Borneo in southeast Asia. However, a previously unknown population has been recorded in West Kalimantan.
Fangfangia spinicleithralis is a species of cyprinid fish endemic to Indonesia where it is found in the peat swamp forests of Kalimantan Tengah, Borneo. It is the only member of its genus. The genus name Fangfangia honors the Chinese-Swedish ichthyologist Fang Fang Kullander (1962-2010), who specialized in the study of cyprinid fishes.
The giant red tail gourami is a large species of gourami belonging to the family Osphronemidae. It is native to the Southeast Asian island of Borneo, where only known from the Kinabatangan and Segama river basins in Sabah, East Malaysia, and Indonesia. First described in 1992 based on an aquarium specimen.
The giant gourami is a species of large gourami native to freshwater habitats in Southeast Asia. It has also been introduced elsewhere. The species is commercially important as a food fish and is also farmed. It can be found in the aquarium trade, as well. The species has been used for weed control on highly invasive aquatic plants like Salvinia molesta, as the giant gourami can be a voracious herbivore.
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.

Rasbora marinae, or Marina's rasbora, is a recently described species of cyprinid fish in the genus Rasbora, in 2020. Several Rasbora specimens from 1996 - 2005, resembling R. cephalotaenia were examined and found to be a new species, due to their unique body pattern in adulthood.
