Unfortunately the prisitine environment form where this fish comes is being threatened by overfishing (much of it for the aquarium trade) and industry, with an oil development being built at one end of the lake during the 1990s. M. lacustris has therefore been given "vulnerable" status on the IUCN red list. The lake was designated a Wetland of International Importance in 1998, as both it and the Kikori Basin where it lies contain some of the earth's greatest biodiversity in terms ...

Type locality is 'Netravati River, Dharmasthala, Karnataka State, India', with the species subsequently recorded from the Kabini (aka Kabani) River basin and it may be endemic to these two drainages. While the Netraviti flows through Karnataka in its entirety before emptying into the Arabian Sea just south of the city of Mangalore, th...

Populations from the upper Pearl River (Nanpan Jiang basin) differ in several morphological characters from those inhabiting Guangdong, Guangxi, and Guizhou Provinces, and Hainan Island. Those from Vietnam also seem to be different (Gan et al., 2009), the implication being that there may be several species currently included under the name M. lineata.

This species appears endemic to the upper rio Madeira basin in Bolivia and Brazil. Records exist from the Río Mamoré and Río Guaporé drainages in Bolivia (where the Guaporé is known as the Iténez) and Brazil plus the upper Río Orthon (ríos Tahuamanu and Manuripi). Type locality is 'sand-bank in the Rio Marm...

Known from the middle Mekong basin in Laos and Thailand, including the Mun tributary drainage on the Khorat Plateau in northeastern Thailand, plus the Chao Phraya and Mae Klong watersheds in central and western Thailand, respectively. In the Mekong system it may also occur further upriver in Yunnan province, China, while the Khone Falls in Laos appear to represent its downstream limit.

Known from the middle Mekong basin in Laos and Thailand, and may be endemic to the Khorat Plateau. Records exist from the Mun and Songkhram watersheds in northeastern Thailand, and a number of Mekong tributaries in laos, including the Nam Mang and Nam Kou drainages. Type locality is 'Nam Mang downstream of Ban Thabok, between 18°22'25"N, 103°13'30"E, and about 1 kilometer upstream, Vientiane Province, Laos'.

Known only from a single cave system (Tham Sai Yok Noi) near the town of Nam Tok Sai Yok Noi, Sai Yok district, Kanchanaburi Province, Thailand. The headwater stream running through the cave is part of the Khwae Noi river basin, itself a tributary of the upper Mae Klong system. 621 metres of the cave system has repor...

Described from close to the city of Beira, Mozambique and for many years thought widely-distributed between the Kruger National Park, South Africa to the Kwa-Kwa River north of the Zambezi delta. Populations from the south and north of this range exhibiting differences in colour pattern and morphology have now been described as N. pienaari and N. krysanovi, respectively, meaning N. rachovii sensu stricto is restricted to the area between the lower Pungwe and Zambezi river basins in eastern Mozambique.

Described from 'Etok stream near Chanderkhong, southern watershed of the Naga Hills, Manipur, Assam', located within the Chindwin River basin in northern India. The Chindwin is the major tributary of the Ayeyarwady/Irrawaddy River and most of it flows within Myanmar although two of its own tributaries, the Manipur and Yu rivers, originate in the Indian states of Manipur and Nagaland.

Type locality is the town of Luxian, located north of Luzhou city, Sichuan province, southwest China. Luxian lies on the Laixi River, one of several tributaries converging with the main Yangtze river channel near Luzhou and forming part of the latter's upper drainage basin. The full extent o...

Prior to description this species was considered to represent, and traded as, A. rubidipinnis, but that species is apparently endemic to the lower Irrawaddy basin in Myanmar and unknown in the aquarium hobby. Male individuals of A. pictilis, A. botia and A. mandalaysensis possess a suborbital slit rather than suborbital flap which immediately distinguishes...

To date the species is known mostly from the upper Ayeyarwady River basin in northern Myanmar where it's been collected close to the city of Myitkyina in Kachin State as well as around nearby Lake Indawgyi, the largest inland lake in Southeast Asia and home to ten globally threatened bird species. The lake and surrounding area were designated a protected zone by the Ministry of Ecotourism in 1999 and now form the Indawgyi Lake Wildlife Sanc...

Know as the pirapitinga in its native countries, this is the one of the largest species of scaled fish found in the Amazon basin. This alone should tell you much of what you need to know about its suitability as an aquarium inhabitant. In reality it's debatable as to whether the species should be considered an aquarium subject at all. While pacu rarely reach their maximum size in captivity, they're still easily capable of growing to a couple of feet in length. The myth that fish will o...

Mostly collected in the 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. P. leopardus was described from the Rupununi River in Guyana and the identity of this fish thus remains unconfirmed. This 'species' is also traded simply as 'leo...

Type locality is given as 'Kuala Tahan, Pahang (King George V National Park)' which corresponds to the village of Kuala Tahan in Pahang state, central Peninsular Malaysia. The settlement is located at the confluence of the Tahan and Tembiling Rivers which form part of the Pahang river basin, while the national park was re...

Recorded from numerous river basins in Vietnam, Cambodia, Laos, Thailand, and Peninsular Malaysia, including the Mekong, Chao Phraya, Mae Khlong, Chanthaburi, Tapi, Golok, Terengganu, Pahang, Endau, and Muar. Type locality is 'Kratt, southeastern Siam', which corresponds to modern-day Trat Province, Thailand.

Type locality is 'Mae Nam Huey Bon, kilometer 45 on road from Amphoe ThaWang Pha to Amphoe Chiang Kham, Chiang Rai Province, Thailand', and this species appears restricted to the Mekong and upper Chao Phraya river basins in northern Thailand and northern Laos. The specimens pictured here were collected from th...

Type locality is 'Central Sumatra, Indonesia', with additional records existing from Cambodia (Mekong drainage), Peninsular Malaysia (Perak River), Sumatra (from the Siak River, Riau province to the Musi River, South Sumatra (Sumatera Selatan) province) and Borneo (south and westwards from the Belait river basin in Brunei Darussalam to the Sambas drainage in West Kalimantan (Kalimantan Barat) province, Indonesia and probably in Sarawak, Malaysia).

The precise extent of this species' range is unclear. The majority of records pertain to the lower rio Xingu basin in the state of Pará, northern Brazil, including middle and lower reaches of its major tributary the rio Iriri, although the type locality is in Mato Grosso state several hundred kilometres upstream. There also exist a handful of records from the rio Jamanxim (a major affluent of the rio Tapajós which drain...

Known from various parts of the middle and upper Mekong river basins with record existing from the Nam Tha, Nam Ou, Nam Khan, Nam Lik, Nam Ngum and Nam Mang tributary systems in Laos, the Nam Noeua (a tributary of Nam Ou) in Vietnam, and the Mae Nam Kok in Thailand. Occurrences in the Chao Phraya drainage in central Thailand most likely refer to the congener R. chiengmaiensis.
