SPECIES PROFILE

Nemacheilus pallidus KOTTELAT, 1990

Classification

Order: Cypriniformes Family: Nemacheilidae

Distribution

A relatively widespread species native to the Mae Klong and upper Chao Phraya river systems in Thailand plus the Mekong basin in Thailand, Laos, Cambodia and Vietnam, where it also occurs in the Dong Nai drainage. Type locality is ‘Huai Mae Phlung from Ban Pong (18°42’N, 99°58’E), to 17 kilometers upstream, Mae Nam Yom basin, Lampang Province, Thailand’.

Habitat

Inhabits streams and small rivers with clear to turbid water, variable flow and substrates of mud, sand or small rocks. In the Nam river, Loei province, northeastern Thailand, it was collected from a shallow (

20 cm deep), moderately-flowing stretch with pebble substrate alongside Schistura nicholsi, Homaloptera smithi, Lepidocephalichthys hasselti, Acanthopsoides gracilis, Rasbora borapetensis and Amblyceps mangois. It was also recorded from a shallow backwater with sandy substrate and direct sunlight in the Siem Reap river, Cambodia.

Maximum Standard Length

Aquarium SizeTop ↑

An aquarium with a base measuring 60 ∗ 30 cm or more is recommended.

Maintenance

Not difficult to maintain under the correct conditions meaning we recommend designing the aquarium to resemble a flowing stream or river with a substrate of variably-sized rocks, sand, fine gravel and some large water-worn boulders. This can be further furnished with driftwood branches arranged to form a network of nooks, crannies and shaded spots. While the majority of aquatic plants will fail to thrive in such surroundings hardy genera such as Microsorum, Bolbitis or Anubias spp. can be grown attached to the décor.

Like many fishes that naturally inhabit running waters it’s intolerant to the accumulation of organic wastes and requires spotless water at all times in order to thrive. It also does best if there is a high level of dissolved oxygen and a decent level of water movement in the tank so external filters, powerheads, airstones, etc., should be employed in order to obtain the desired effect. As stable water conditions are obligatory for its well-being this fish should never be added to biologically-immature aquaria.

Water Conditions

Temperature: 23 – 26 °C

Hardness: 36 – 215 ppm

Nemacheilus species are omnivorous although the bulk of their diet consists of small insects, worms, crustaceans and other zooplankton with only relatively small amounts of plant matter consumed, mostly via the stomach contents of prey items.

In the aquarium they will accept dried foods of a suitable size but should not be fed these exclusively. Daily meals of small live and frozen fare such as Daphnia, Artemia, bloodworm, etc., will result in the best colouration and condition.

Behaviour and CompatibilityTop ↑

Fishes which inhabit similar biotopes in nature constitute the best options, especially peaceful, open water-dwelling cyprinids since the presence of one or two schools can make a visible difference to the confidence of this naturally reclusive loach.

Other possibilities include balitorids like Gastromyzon, Pseudogastromyzon, Beaufortia, and Sewellia, plus Crossocheilus and Garra species. Some similarly-shaped relatives such as other Nemacheilus, Acanthocobitis, and Schistura spp. are excessively territorial or otherwise aggressive, although a combination may work in larger aquaria.

This species is peaceful with conspecifics and seems to appreciate being maintained in a group so the purchase of four or more specimens is highly recommended.

Sexual Dimorphism

Adult females are likely to be slightly larger and heavier-bodied than males. Mature males possess a suborbital flap with a pair of tubercules on the inner face and 6-10 rows of tubercules above and below the lateral line between the pelvic and anal fins. The first branched pectoral-fin ray is thickened with a few tubercules towards the tip, while there are 3-4 rows of tubercules on each branched pelvic-fin ray 2-6.

Reproduction

NotesTop ↑

N. pallidus can be distinguished from the majority of congeners by body patterning comprising 14-19 short, dark vertical bars on each flank, 13-16 saddle-like markings running along the dorsal surface, a dark spot on the caudal peduncle at the termination of the lateral line, and a dark blotch in the lower half of the first few dorsal-fin rays.

The similar-looking N. masyai is sometimes traded as N. pallidus, but the two can be told apart by body depth (14.8-19.1 % in N. pallidus vs. 12.6-17.6 % SL in N. masyai), interorbital width (5.7-8.0 % vs. 4.9-6.8 % SL) and the fact that in N. pallidus the dark body bars and saddles are thinner than the light-coloured interspaces between (vs. wider in N. masyai).

Following Kottelat (1990) the genus Nemacheilus is characterised by a combination of characters as follows: elongate body; complete lateral line; presence of enlarged scales above and below the lateral line in some species; caudal-fin forked to deeply forked with enlarged upper lobe; large eye; small, strongly arched mouth; lips usually thin; usually no median interruption in upper lip; upper jaw with processus dentiformis (a tooth-like projection); no median notch in lower jaw; long barbels; males usually with suborbital flap, pectoral-fin rays 2-6 thickened and with rows of tubercules.

The family Nemacheilidae is widely-distributed across most of Eurasia with the Indian subcontinent, Southeast Asia and China representing particular centres of species diversity. It was first proposed as a genetically-distinct grouping in 2006, and according to current knowledge contains over 30 genera of which the most well-known in the aquarium hobby include Aborichthys, Acanthocobitis, Barbatula, Mesonoemacheilus, Nemacheilus, Physoschistura, Schistura, and Yunnanilus.

These were previously considered members of the family Balitoridae, subfamily Nemacheilinae, but phylogenetic studies have revealed that though closely related Balitorid and Nemacheilid loaches did not evolve from the same common ancestor and represent separate genetic lineages. The revised Balitoridae numbers over 30 genera including some popular aquarium subjects such as Annamia, Beaufortia, Gastromyzon, Homaloptera, Liniparhomaloptera, Pseudogastromyzon, Sewellia, Sinogastromyzon, and Vanmanenia spp.

Исчезнувший (вымерший) вид[7] (англ. Extinct, EX) — охранный статус, присваиваемый организму или группе организмов (таксонов), не встречавшихся как в дикой природе с момента последнего официально зарегистрированного наблюдения, так и не сохранившихся в неволе. В качестве отправной точки исчезновения обычно рассматривается смерть последнего представителя данного вида, хотя способности размножаться и восстанавливаться могут быть потеряны ещё до этого времени. Поскольку потенциальный ареал вида может быть очень широким, определение отправной точки исчезновения достаточно трудоёмкое занятие.

Исче́знувшие в ди́кой приро́де[6] (англ. Extinct in the Wild, EW) — охранный статус, присваиваемый биологическим видам или таксонам, представители которых сохранились только в неволе..

Находящиеся на грани полного исчезновения[5] (англ. Critically Endangered, CR) — охранный статус, который присваиваетcz биологическим видам или инфравидовым таксонам, имеющим чрезвычайно высокий риск исчезновения в дикой природе. Отнесение таксонов к этой категории означает, что их численность сократилась или может сократиться на 80% в течение трёх поколений. МСОП не относит таксоны к категориям исчезнувших (EX, EW) до тех пор, пока не будет осуществлено масштабных специальных исследований, в связи с этим имеется вероятность, что таксоны, имеющие статус “Находящиеся на грани полного исчезновения”, в действительности уже исчезли..

Вымирающие виды[4] (англ. Endangered species, EN) — охранный статус, который присваивается биологическим видам, которые подвержены угрозе вымирания из-за своей критически малой численности либо воздействия определенных факторов окружающей среды. Вымирающий вид — обычно таксономический вид, но может быть и другой эволюционно значимой единицей, например подвидом.

Находятся в уязвимом положении[3] (англ. Vulnerable species, VU) — охранный статус, присваиваемый биологическим видам, которые находятся под риском стать вымирающими. Они нуждаются в мониторинге численности и темпа размножения, а также в мерах, способствующих сохранению их среды обитания. Иногда такие виды хорошо размножаются в неволе, но сохраняют статус «Находятся в уязвимом положении», так как существует угроза для дикой популяции вида..

Бли́зкие к уязви́мому положе́нию[2] (англ. Near Threatened, NT) — охранный статус предоставляется видам или нижним таксонам, которые могут рассматриваться как находящиеся под опасностью исчезновения в ближайшем будущем, хотя в настоящее время они не претендуют на статус уязвимых. МСОП отмечает необходимость пересмотра статуса таксонов, близких к уязвимому положению, часто или через определённые промежутки времени.

Вызывающие наименьшие опасения[1] (англ. Least concern, LC) — охранный статус, который Международный союз охраны природы присваивает биологическим видам или инфравидовым таксонам, не входящим в какую-либо иную категорию. К ним относятся наиболее распространенные и процветающие виды. Они, как правило, не занесены в Красные книги, однако их инфравидовые таксоны могут находиться под угрозой.

Виды, угроза для которых не оценивалась[1] (англ. Not Evulated, NE) — Это категория видов, которые занесены в Красную книгу исчезающих видов МСОП, но еще не были оценены. Категория «нет оценки» не указывает на то, что вид не находится в зоне риска исчезновения. Причина классификации является недостаточность данных, чтобы отнести в группу какого-либо риска.

Виды, для оценки угрозы которым недостаточно данных[1] (англ. Data Deficient, DD) — Категория, применяемая МСОП, когда имеющейся информации недостаточно для надлежащей оценки охранного статуса и для того, чтобы была определена оценка риска исчезновения вида. Таксон, отнесённый к этой категории, может быть достаточно хорошо изучен, но при этом не хватает современных актуальных данных о численности популяции и ареала. Категория «Недостаток данных» не является категорией угрозы исчезновения. Включение таксона в данную категорию указывает, что требуется больше информации о состоянии вида.

Этимология (1)

Название вида происходит от латинского слова [pallidus] – бледный и связано оно с с бледной окраской прелставителей вида.

Параметры воды (8)

Рекомендуется содержать цихлид оз. Малави в аквариуме с водой при значениях рН от 7,0 до 8,5, хотя возможны и незначительные отклонения, в ту или иную сторону, особенно для видов давно закрепившихся в аквакультуре. Подробнее о pH читайте в статье Сергея Аникштейна “pH и буфер”. Желательно, поддерживать постоянную температуру в диапазоне между 23 и 28°С. Перегрев до 32°С и выше, может оказаться для рыб смертельным. Обязательна регулярная аэрация и фильтрация воды, а также регулярные, не реже 1 раза в неделю, подмены 10-20% воды в аквариуме на свежую или организация проточных подмен.

Nemacheilus platiceps

Nemacheilus platiceps is a species of ray-finned fish in the genus Nemacheilus . It has been recorded in the lower Mekong basin in eastern Thailand, central and southern Laos, Cambodia and Vietnam. Its habitat is stretches of rivers with a gravel substrate where there is a moderate to rapid current in the lowlands and in foothills. It is consumed locally in subsistence fisheries and is occasionally found in the aquarium trade. [1]

SPECIES PROFILE

Nemacheilus platiceps KOTTELAT, 1990

Etymology

Nemacheilus: from the Greek nēma, meaning ‘thread’ or ‘filament’ and cheilos, meaning ‘lip’ in reference to the furrowed lip in members of this genus.

Classification

Order: Cypriniformes Family: Nemacheilidae

Distribution

Native to the Mekong river basin in Laos, Thailand, Cambodia and Vietnam and also known from the Dong Nai system in southern Vietnam. Beamish et al. (2008) recorded it from the Chao Phraya system in central Thailand but this may represent a case of misidentification.

Type locality is ‘Trang Bom, Vietnam’.

Habitat

Has been collected from shallow, slow-moving pools of hill streams where leaf litter collects and moderately to fast-flowing habitats with gravel substrate.

Flow, depth and turbidity presumably increase during the annual monsoons but little else is known about its ecology.

Maximum Standard Length

The largest officially-recorded specimen measured 61 mm.

Aquarium SizeTop ↑

An aquarium with a base measuring 60 ∗ 30 cm or more is recommended.

Maintenance

Not difficult to maintain under the correct conditions; we strongly recommend keeping it in a tank designed to resemble a flowing stream or river with a substrate of variably-sized rocks, sand, fine gravel, and some water-worn boulders.

This can be further furnished with driftwood branches arranged to form a network of nooks, crannies, and shaded spots, thus providing broken lines of sight. While the majority of aquatic plants will fail to thrive in such surroundings hardy types such as Microsorum, Bolbitis, or Anubias spp. can be grown attached to the décor.

Though torrent-like conditions are unnecessary it does best if there is a high proportion of dissolved oxygen and some water movement in the tank meaning power filter(s), additional powerhead(s), or airstone(s) should be employed as necessary.

Like many fishes that naturally inhabit running water it’s intolerant to accumulation of organic pollutants and requires spotless water in order to thrive, meaning weekly water changes of 30-50% tank volume should be considered routine.

Water Conditions

Temperature: 23 – 26 °C

Hardness: 36 – 215 ppm

Nemacheilus species are omnivorous although the bulk of their diet consists of small insects, worms, crustaceans and other zooplankton with only relatively small amounts of plant matter consumed, mostly via the stomach contents of prey items.

In the aquarium they will accept dried foods of a suitable size but should not be fed these exclusively. Daily meals of small live and frozen fare such as Daphnia, Artemia, bloodworm, etc., will result in the best colouration and condition.

Behaviour and CompatibilityTop ↑

Fishes which inhabit similar biotopes in nature constitute the best options, especially peaceful, open water-dwelling cyprinids since the presence of one or two schools can make a visible difference to the confidence of this naturally reclusive loach.

Other possibilities include rheophilic loaches from genera such as Gastromyzon, Pseudogastromyzon, Beaufortia, and Sewellia, plus benthic cyprinids like Crossocheilus and Garra species.

Some similarly-shaped relatives such as other Nemacheilus, Acanthocobitis, and Schistura spp. are excessively territorial or otherwise aggressive, although a combination may work in larger aquaria.

This species is peaceful with conspecifics and seems to appreciate being maintained in a group so the purchase of four or more specimens is highly recommended.

Sexual Dimorphism

Adult females are likely to be slightly larger and heavier-bodied than males. Mature males possess a superficial suborbital flap.

Reproduction

NotesTop ↑

This species is only occasionally available in the aquarium trade.

It’s distinguished from congeners by a combination of characters including: 12-16 dark, irregular, vertical bars on body, usually split vertically; lips without furrows; incomplete lateral line, reaching to anus; subequal (almost equal) caudal-fin lobes; dark blotch in lower half of caudal-fin base.

Kottelat (1990) found that in Cambodian specimens the body bars are more regular and only tend to be split in large adults.

Following Kottelat (1990) the genus Nemacheilus is characterised by a combination of characters as follows: elongate body; complete lateral line; presence of enlarged scales above and below the lateral line in some species; caudal-fin forked to deeply forked with enlarged upper lobe; large eye; small, strongly arched mouth; lips usually thin; usually no median interruption in upper lip; upper jaw with processus dentiformis (a tooth-like projection); no median notch in lower jaw; long barbels; males usually with suborbital flap, pectoral-fin rays 2-6 thickened and with rows of tubercules.

The family Nemacheilidae is widely-distributed across most of Eurasia with the Indian subcontinent, Southeast Asia and China representing particular centres of species diversity.
