This species can be distinguished from congeners inhabiting the Red River basin in Yunnan province, China, by the following combination of characters: no barbels; 46-52 lateral line scales; 16 circumpeduncular scales; pharyngeal teeth in 3 rows, 2.4.5-5.4.2; snout rounded, no secondary rostrum, no longitudinal...

Prior to its description, G. rotundinasus was considered to represent the congener G. gravleyi, but the latter is now accepted to occur only in the Salween and Manipur river basins. These two are separated from all other Garra species in China and Southeast Asia by possession of a weakly-devel...

In fact G. farragus and G. ocellatus represent one of 12 pairs of cryptospecies to be found in the genus, differing in subtle aspects of patterning. Cryptospecies are defined as morphologically similar, but reproductively isolated species which in fishes often inhabit adjacent river basins but in some cases occur sympatrically. The phenomenon may be a result of parallel evolution, and is not normally considered to represent an early stage of speciation.

Recorded from the middle to lower Mekong river basin in southern China (Yiunnan province), Laos, Thailand, and Cambodia, plus the Chao Phraya watershed in central Thailand. Type locality is 'Thailand: Lam Ton Lang, a tributary of Menam Sak [Mae Nam Pa Sak; Ban Lam Thong Lang, village northwest of Pakjong'.

Widepread in eastern Asia between the Yangtze and Amur river basins, including China (mainland and islands of Taiwan and Hainan), Korea, Mongolia, Russia, and Japan. It probably been introduced to Vietnam and Laos, or records from these countries represent another species.

Most records pertain to the Mekong River basin downstream of the Khone waterfalls in Laos and Cambodia, but this species is also known from some smaller river drainages in southern Thailand, including parts of the Mae Klong system. Type locality is 'Khlong Fit at Ban Kraduk Chang, road 3157 from Trat to borai, about 2-3 kilometers after junction w...

Described from close to the village of Ban Khiri Wong, Nakhon Si Thammarat Province, southern (peninsular) Thailand but since recorded throughout much of the country, including the Chao Phraya and Mekong river systems. It's also known from Peninsular Malaysia and parts of the Mekong basin in Laos, Cambodia and Vietnam. Rainboth (1996) considered it 'probably the commonest member of the genus in the Mekong' and in a 2008 study of balitorid habitats in centra...

Described from Kota Tinggi district, Johor state, Peninsular Malaysia but since recorded throughout much of the country as well as parts of the the Mekong river system in Thailand, Laos, Cambodia and Vietnam plus the Kapuas and several other river basins in Kalimantan Barat (West Kalimantan) province, Indonesian Borneo. In the Kahang River, part of the Endau drainage in Jo...

L136 and its variants are collected in the rio Negro basin, Amazonas state, Brazil, and in particular the rio Demini, a northern tributary flowing into the central Negro in the municipality of Barcelos. Collection details for LDA05 and LDA06 are currently unclear but presumably in the vicinity. This unidentified 'species' is highly variable in terms of colour pattern, and it has been assigned a ser...

Type locality is 'Rio das Mortes, some 100 km before its confluence with the Braço Maior of the Rio Araguaia (the western border of the Isla do Bananal). State of Mato Grosso.' The das Mortes is a principal tributary of the Araguaia, itself the major affluent of the rio Tocantins within the lower Amazon basin in central and western Brazil, although the full range of H. amandae within the Araguaia system is unclear.

Known only from headwaters of the upper Paraná river basin in the Federal District plus the neighbouring state of Goiás, central Brazil. Type locality is 'Planaltina, Lagoa Fervedeira, Goiás, Brazil' with additional records existing mostly from the rio São Bartolomeu including the Bananal, Santa Maria-Torto and Gama tributary systems.

This species is a popular aquarium fish and is bred on a commercial basis in several countries, with a selectively-bred albino form also available. Wild specimens are rarely collected due to the low price of the farmed fish, but the origin of the commercial strain is questionable. The species was considered endemic to the rio Tapajós basin, but in the early 1990s fish appearing identical to the aquarium form were photographed in the...

Known from the middle and lower Mekong basins in Laos, Thailand, Cambodia, and Vietnam, plus the Dong Nai drainage in central Vietnam. Type locality is 'Rapids of Dang-nai, Bien Hoa Province, Thailand', which corresponds to what is now the city of Biên Hòa in Đồng Nai province, southern Vietnam.

This species is known from the rio Negro within the Brazilan Amazon basin and upper Río Orinoco system in Venezuela. Type locality is 'Rio Adujá, Rio Itú, tributary of middle Rio Negro, Amazonia, Brazil'.

Widely-distributed throughout the Amazon, Orinoco, Essequibo, and Tocantins river systems in Brazil, Peru, Bolivia, Ecuador, Colombia, Venezuela, and Guyana. Type locality is 'Rio Cupai [= Rio Cupari], Rio Tapajós basin, Amazon River drainage, Pará State, Brazil'.

This species has been recorded from the Guaporé, Madeira, Branco, Trombetas, and Urubu river systems within the Amazon river basin, Brazil. Type locality is 'Igarapé Jatuarana, 5 kilometers above Samuel, Rio Guaporé, Rondonia, Brazil'.

Native to the lower Amazon river basin in Brazil with some populations exhibiting differences in colour pattern to one another, particularly in respect of the degree of red and blue pigmentation on the body and fins. Type locality is given simply as 'Amazon River, Brazil'. Field observations suggest it to display a pref...

Known from Great Lakes Erie and Michigan with distribution extending south through the Mississippi River basin to the Gulf of Mexico drainages where it's said to occur between the lower Apalachicola River in Florida and the Nueces River in Texas. It may also be found in the Rio Grande which forms the border between Mexico and the United States further south where records include Falcon International Reservoir, for example.

Type locality is given simply as 'Amazon River, Brazil' and according to current thinking this species has a huge natural range encompassing the Amazon River system in Brazil and Peru plus the Paraná-Paraguay drainage in southern Brazil and Paraguay and rio São Francisco basin in southern Brazil. Specimens in our images were collected fro...

Described from Sichuan province, southwestern China (presumably the upper Yangzte River, aka Chang Jiang, drainage) and also known from parts of the Pearl River (Zhu Jiang) basin in Guangxi Autonomous Region. The latter area is one of the most populous and industrialised in China meaning much of the main river channel is now highly polluted. Its relatively wide distribution probably explains why it's commoner in the aquarium hobby than the similar-looking...
