It can be further distinguished from other species in the genus by colour pattern consisting of a dark, horizontal P stripe originating around mid-body, where it’s relatively faint, this becoming thicker and darker in the posterior portion of the body and terminating at the base of the caudal-fin. Among congeners it’s most similar to D. chrysotaeniatus but that species lacks the infraorbital process, has three rows of pharyngeal teeth and the P stripe extends to the end of the caudal-fin rays.

This species is poorly known and first appeared in the hobby during 2005 but has rarely been seen since, probably because its natural waters lie outside the range of most commercial collectors.
It can be distinguished by a combination of characters including: lateral line complete; infraorbital process absent; two pairs of short barbels; 8-9 branched dorsal fin rays; 12-13 branched anal fin rays; P stripe originating above pelvic fin and extending to en…

The type series was collected during the dry season from localities with varying gradient both within the Nam Leuk mainstream and smaller tributaries. In the tributaries the fish were found congregating in pools some of which were isolated on steep slopes. All habitats above Tad Leuk falls were characterised by clear to very clear water under forest cover while below the falls they were dominated by exposed basalt slabs with some underground water channels.

Tiger Hillstream Loach
March 13th, 2012 — 1:25pm
S. lineolata was first recorded by Diard over 150 years prior to its 'rediscovery' in the early-1990s. It became available to the aquarium trade in the mid-2000s and swiftly established itself as one of the more popular balitorids in the hobby due to its attractive body markings and ease of breeding. It's also sold under the names 'reticulated hillstream loach', 'Vietnamese hillstream loach' and 'gold ring butterfly sucker'.
It's difficult to…

Fish sold under the name S. zonata are sporadically available in the aquarium trade but the majority appear to be the congener S. octozona.
The genus currently contains just three members all of which are known only from the Mekong basin. S. octozona is the type species and separ…

This species exhibits some interesting behaviour including a degree of social interaction plus the ability to cling to vertical or overhanging surfaces. It’s sometimes sold under the name ‘serpent loach’.
The genus currently contains just three members all of which are known only from the Mekong basin. S. octozona is the type species and separated from the others mainly by body patterning which consists of 7-8 dark bars on each flank, these extending the full depth of the body and much wider than the pale interspaces between.

This species is only traded occasionally. 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; inco…

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).

Laos Blackline Torpedo Loach
March 13th, 2012 — 1:25pm
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 rheoph…

Giant Kuhli Loach
March 13th, 2012 — 1:25pm
It’s included in the P. kuhlii group of closely-related species and can be distinguished from other members by the following combination of characters: 8-11 very broad, quadrangular, regular dark body bars; orange base body colour; caudal-fin either entirely black or with a large black blotch at the base and a submarginal dark bar or row of spots. The latter feature can be useful in identifying young or newly-imported, undernourished specimens which can…
