This is one of the most frequently-traded members of the genus and is an excellent choice for those new to keeping loaches.

It’s distinguishable from congeners by a combination of characters including: relatively large adult size (to at least 80 mm SL); rounded/truncate caud…

This species is traded on a fairly regular basis and is similar in appearance to some congeners, most notably S. bella, S. mahnerti, S. multifasciata, S. poculi, S. reticulata, S. longa, S. conirostris and S. udomritthiruji.

This assemblage has been referred to as the Schistura multifasciata ‘group’, and members share a…

The type locality originally consisted of a shallow (0.5 – 1.5 m deep) stream with a substrate of rocks and boulders and flow varying from ‘moderate to swift’.

When the holotype was collected there in 1980 sympatric species included Acanthocobitis zonalternans, Puntius orphoides, Pethia ticto, Raiamas guttatus, Barilius barnoides, Mystacoleucus argenteus and Mastacembelus armatus plus unidentified members of Crossocheilus an…

At one locality close to Ban Na Hwai, Chiang Mai Province, Thailand L. hasselti was collected from a shallow (<0.5 m) pool in a swampy zone between forest and rice fields. The substrate was of mud, there was no aquatic vegetation and it was being used as drinking water by local animals, with the only effluent connected to a 'small creek'. Other species found there were Physoschistura pseudobrunneana, Rasbora hobelmani and Systomus cf. orphoides.

The type locality is a stream with a mixed substrate of mud and stones which flows swiftly through an area of bamboo forest so is quite well-shaded. At time of collection the water was clear but slightly tannin-stained and sympatric species included Pethia thelys, Puntius sophore, Devario strigillifer, Rasbora daniconius, R. rasbora, Acanthocobitis botia, Notopterus notopterus, plus unidentified species of Oreichthys, Parambassis, Xenentodon, and Mastacembelus.

Apparently discovered close to the coastal town of Gwa in Rakhine State, western Myanmar. Rakhine is largely cut off from the rest of the country by the Rakhine Yoma/Arakan mountains which form a natural barrier along its eastern side.

Rakhine is located within a tropical monsoon region and has a pronounced rainy season between May and October, while at other times it can be quite dry. The streams thus swell in depth by a metre or mo…

This potentially-undescribed species first became available in 2002, and males and females were marketed as ‘Danio sp. hikari yellow’ and ‘D. sp. hikari blue’, respectively. Subsequent DNA testing in the United States revealed them to be the same species and genetically distinct from the very similar B. kerri. It can be told apart as the central body (P) stripe always extends into the caudal fin whereas in B. kerri it terminates at the caudal peduncle. Only a single population of B. kerri was sampled in the stu…

This species was formerly included in the genus Microrasbora although it’s long-been considered a danionin by certain authors, e.g., Kottelat and Witte (1999) and was placed within the genus Danio for a period.

In the aquarium trade it’s marketed under various names including ’emerald dwarf danio’, ‘thick band purple zebra danio’ and ‘cross-banded dwarf rasbora’.

This apparently undescribed species has been available in the hobby since around 2006 and has been traded under several trade names of which others include ‘tri-band sumo loach’ and ‘chubby loach’.

The name ‘Sumo II’ is now in wide use to distinguish it from the real S. balteata since both have been traded as ‘Sumo loach’…

This fish is one of several sometimes imported and sold as Oreichthys cosuatis or O. parvus which has led to considerable confusion. It appears to be an undescribed species and can be most easily identified by the absence of a dark marking in the dorsal-fin of adult males (vs. presence in O. cosuatis and O. parvus) and possession of a large, well-defined black blotch on the caudal peduncle ( vs. absent in O. cosuatis, smaller and less well-defined in O. parvus).
