Nemacheilus Saravacensis


Maximum Standard Length
Unconfirmed but at least 40 - 50 mm. 

Minimum Tank Size
A tank with a base measuring 60 cm x 30 cm or more is recommended. 

Tank Setup
Not difficult to maintain under the correct conditions; we strongly recommend keeping it in a tank designed to resemble a flowing stream/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.

Like many fishes that naturally inhabit running water it´s intolerant to accumulation of organic pollutants and requires spotless water in order to thrive. Though torrent-like conditions are unnecessary it does best if there is a high proportion of dissolved oxygen and decent water movement in the tank so a powerful external filter/powerhead or two should be added, and ideally a rivertank manifold installed to provide unidirectional flow. While the majority of aquatic plants will fail to thrive in such surroundings hardy types such as Java fern, Bolbitis or Anubias spp. can be grown attached to the décor. Weekly water changes of 30-50% tank volume should be considered routine. 

73 - 79°F /23 - 26°C 

pH Range
4.5 - 7.0 

1 - 10°H 

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. 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. 


Fishes which inhabit similar biotopes in nature, especially those which swim in open water such as Danio, Devario, Mystacoleucus, smaller Barilius plus some Puntius and Rasbora species constitute the best options, and one or two decent-sized 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. Similarly-shaped relatives such as other Nemacheilus, Acanthocobitis and Schistura spp. are not really recommended although a combination may work in larger aquaria.

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