There appears to be some discrepancy between Smith’s original description and Kottelat (1990) in that Smith states the fish is a member of a group of species lacking an ocellus at the upper caudal-fin base, whereas Kottelat mentions the presence of ‘a black spot at upper extremity of caudal-fin base, surrounded by a whitish area’.

This species is sometimes traded for aquaria but its name also appears to have been widely misapplied to other fishes.

It can be identified via the following combination of characters: presence of 8-10 quite regular dark bars…

The type locality consisted of remnant ephemeral pools in otherwise dry agricultural land, and many adults were collected from such habitats.

Other species present included the congener L. hasselti plus members of Anabas, ‘Puntius‘, Rasbora, Channa, and Hampala.

On Koh Chang one habitat consisted of a stream flowing from the waterfall Nam Tok Mai Yom which empties into the Gulf of Thailand after less than 1 km.

The stream was dry in its lower reaches and had a substrate of boulders and pebbles. Sympatric fi…

This species is distributed in the middle Mekong River basin in north and northeastern Thailand, Myanmar and Xishuangbanna Dai Autonomous Prefecture, Yunnan province, southern China, and is also known from the Nam Beng, Nam Tha and Nam Yuoan drainages in Laos.

Type locality is ‘Laun We (Loi Mw…

Apparently restricted to slow-moving or standing freshwater habitats such as marshes, temporal swamps and floodplains where aquatic vegetation and submerged grasses proliferate.

One locality consisted of undisturbed marshland with lightly tannin-stained water and dense growth of Vallisneria spp.

Though this species appears on ornamental trade lists quite often the name appears to be routinely misapplied to other species, particularly B. doriae.

It can be diagnosed as follows: <30 lateral scales; two black body bands reaching ventral midline posterior to anal-fin; band above anal-fin als...

Appears restricted to highly-oxygenated, fast-flowing riffles of small-to-medium sized streams. These typically contain clear water with substrates of gravel, rocks, boulders, and bedrock with no aquatic plants.

This species is traded for aquaria under various names including ‘butterfly barb’, ‘mackerel barb’, ‘green-barred danio’, and ‘royal opsarius’.

It can be told apart from other memb…

Inhabits well-oxygenated, low-to-medium gradient, slow to moderate-flowing rivers and streams with substrates of gravel, cobbles, larger boulders and exposed bedrock. At the habitat in our image pH was 7.5, temperature 26°C and cond…
