This species is also known as 'leaping barb' and was once quite common in the ornamental trade but is now seldom seen. It can be distinguished from other members of the genus by the following characters: bright blue spot on top of head; series of 4-5 short faint bars on anterior portion of body; 19-23½ branched anal-fin rays; body depth fits 2.1-2.9 times in SL.

This species is almost identical to the wild form of 'P.' semifasciolatus which is best known as the 'golden barb' in the aquarium hobby due to the popularity of a yellowish ornamental strain. The natural colour pattern is greenish in both species, however, and in terms of external characters they're only reliably distinguished by the fact that 'P.' semifasciolatus possesses a pair of prominent maxillary barbels wherea...

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...

Members of the genus are characterised by possessing a particular number of dark vertical bar on each flank, and A. parallens belongs to a group of species with five or six such bars, each of which is two scales in width. Congeners sharing this pattern include A. fasciatus, A. hemispinus (in juveniles only), A. jishouensis, A. kreyenbergii, A. paradoxus, A. spinifer, A. wenchowensis, and A. wuyiensis.

It can be distinguished from congeners by possessing one or two pairs of barbels, a black blotch at the base of the caudal-fin, and rows of dark spots along the lateral scale rows. Members of Cyclocheilichthys are characterised by possessing a serrated dorsal fin spine, 9 branched pelvic fin rays, a conical snout, small, subterminal...

Endemic to the Ganges and Brahmaputra river basins and thus occurs in northern India, Nepal and Bangladesh. Type locality is 'the Yamuna River, and northern rivers of Behar and Bengal'. The distribution of the genus as a whole is interesting because these fish occupy the area that geographically separates Indian and Southeast Asia barbs and it has been theorised that they may represent an evolutionary 'link' species...

This species is occasionally marketed as 'Burmese Rainbow Barb' in the ornamental trade. others may have been exported in small numbers or as bycatch among shipments of other species. It was referred to as Mystacoleucus marginatus for decades, but that name is a simultaneous subjective synonym of M. obtusirostris following Kottelat (2013).

Originally described as a member of Barilius (Annandale, 1918) but Howes (1980a) considered it more closely related to cheline cyprinids (Chela and Laubuca spp.) based on morphological characters and erected the genus Inlecypris for it (Howes, 1980b). Fang (2003) supported Howes' conclusions in her 2003 phylogenetic study of the genus Danio, hypothesising that Inlecypris and Chela together form a sister group to Devario.

Confusion with similar-looking fishes from other genera, such as Garra cambodgiensis, laterally-striped Crossocheilus spp. or Gyrinocheilus aymonieri is not uncommon, and are largely attributable to the use of trade names such as 'false flying fox' or 'Siamese flying fox'. When compared with the other species E. kalopterus exhibits several unique characters but perhaps the simplest way to identify it is by the characteristic white-edged, red and black coloured fins and the presence of two pairs of barbels.

Predominantly a riverine fish preferring clear, well-oxygenated, running waters with substrates of sand, gravel, rock or mud, typically flowing through tropical forest. In the habitat seen in our images sympatric fish species included Barbonymus balleroides, B. collingwoodi, Cyclocheilichthys repasson, C. apogon, Diplocheilichthys pleurotaenia, Garra borneensis, Leptobarbus hosii, and an unidentified Gastromyzon sp.

This species occasionally appears in the aquarium hobby, but the trade is largely reliant on commercially-produced 'tiger barbs' of questionable origin. It is distinguished from congeners by the following combination of characters: lateral line complete; 14 circumpeduncular scales; 21-23+2 scales in the lateral row; dorsal-fin black with red outer band; pelvic fins red.

It can be told apart from other members of the B. pugnax group by the following characters: chin bar absent; prsence of transverse bars in the dorsal-fin; no transverse bars in caudal-fin; green iridescent scales present on opercle and body; anal fin with iridescent, light blue distal band; a pair black markings below the postorbital stripe on the opercle of females and juveniles; anal-fin rays 25-29 (mode 28); lateral scales 28-30 (mode 29); postdorsal scales 10-11 (mode 12); pelvic-fin length 34.8-50.6% SL; head length 33.4-36.8% SL; inter-orbital width 31.7-37.4% HL.

Adult patterning of the different geographical forms can vary considerably though young specimens all possess 5 solid dark bars on each flank and are often confused with those species exhibiting a similar juvenile pattern, particularly B. kubotai. However the horizontal dark bars on the flanks in B. kubotai typically split at quite a young age and/or develop horizontally-orientated 'peaks' whereas those in B. histrionica remain solid for longer and the central bar usually has a pale spot at the top so forms a 'y' shape.

E. octozona can be told apart from congeners by the following combination of characters: bar 1 present; presence of a large and distinct black mark anterior to anus, visible in lateral and ventral views; simple dorsal-fin rays black, sometimes extending onto first branched ray; other rays hyaline or with diffused chromatophores on last dorsal-fin ray, adjacent to upper extremity of bar 6; 25-31 serrae on last simple dorsal-fin ray; uppermost ray of pectoral-fin with faint black margin; width of bar 5 equal to 1-1½ lat...

This species is very rarely-traded since collections of fishes for commercial purposes aren't common in Suriname. It's a member of the nominal G. surinamensis 'group' of closely-related species within the genus and can be identified by a combination of characters including: no dark preopercular marking; six vertical/parallel bars on each flank (normally visible only when the fish are stressed, spawning or preserved); dark, squarish lateral spot positioned within the third vertical bar; sixth (posterior) bar elongate an...

It's a member of the nominal G. surinamensis 'group' of closely-related species within the genus and can be identified by a combination of characters including: presence of dark preopercular markings; seven parallel vertical bars on each flank (normally visible only when the fish are stressed, spawning or preserved); vertical bars four and five meet in such a way that they form a 'Y' shape; dark lateral spot positioned within the third vertical bar; caudal fin reddish with variable pattern of iridescent blue spots and stripes.

B. pinguis is included in the Betta akarensis group/complex of closely-related species within the genus, of which members share the following set of characters: possession of pre-orbital and post-orbital stripes (the post-orbital stripe is faint or interrupted in some species); chin bar present; caudal-fin lanceolate with highly extended median rays in mature males; caudal fin usually with transverse bars; greenish or bluish iridescent scales on body of males in some species; opercle without iridescent scales except in juveniles.

It can be told apart from other members of the B. pugnax group by the following characters: chin bar present; no complete second postorbital stripe on opercle; presence of transverse bars in caudal-fin of males; caudal-fin in males broadly lanceolate; opercle scales iridescent blue; anal-fin with reddish subdistal band and black margin; caudal-fin without dark margin; 25-28 anal-fin rays; 28-31 lateral scales; 11-12 postdorsal scales; length of pelvic fins 26.6-43.8 % SL; length of head 27.5-35.2 % SL; inter-orbital width 32.4-53.0 % HL.

Following Grant (2007) this species is included in the B. dario complex of closely-related species within the genus alongside B. striata. They're characterised by body patterning consisting of a base yellow to golden colour with 7-9 blue, green, grey or black body bars usually with thinner, lighter bars between. In some individuals the...

Within the nominal species grouping suggested by Grant (2007) almost all B. rostrata sold in the hobby are B. sp. 'upper Brahmaputra' with B. rostrata sensu stricto rarely, if ever, available. Trade names include 'Gangetic loach', 'twin-banded loach' and 'ladder loach'. The defining characters of the group are "Pattern consisiting of 8-10 black to dark brown body bars that exhibit pale and numerous spots in juveniles, and in adults the bars can anast...
