H. inspector can be told apart from other described species in the genus by the following combination of characters: colour pattern comprising brown to black base with large whitish to yellow spots; adpressed dorsal-fin not reaching the adipose-fin spine; spots on head much smaller than on rest of body; spots in the upper caudal-fin lobe combining to form bands in adults; 24 plates in the mid-ventral series.

H. wetmorei is distinguished from congeners by the following combination of characters: upper body reddish brown; robust body, not compressed; usually 4½ scale rows between lateral line and dorsal-fin origin; 8-12 rakers on first gill arch; 7-9 predorsal scales; 14 circumpeduncular scale rows; usually two scale rows separating vent and anal-fin; <29 lateral line scales; 9-14 serrations on the spinous dorsal-fin ray; distance between distal serrae on posterior margin of last unbranched dorsal-fin ray much greater than the width of their bases.

Among them it's most similar to I. longicorpus and I. hugowolfeldi but can be distinguished by the following combination of characters: body patterning consisting of 9-13 dark vertical bars along the flanks plus a small dark spot at the base of the upper caudal-fin lobe; no black blotch or markings posterior to the operculum; reduced lamina circularis in males; interorbital width measures 14.7-17.8% o...

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.

This species is likely to be traded for aquaria but probably misidentified as the very similar-looking K. cyrptopterus with which wild populations were formerly considered conspecific. These two are closely-related and can be distinguished from congeners by the dorsal profile lacking a nuchal concavity (vs. possessing a nuchal concavity) and possessing short maxillary barbels (extending to the pectoral-fin base vs. ext...

This species can be identified by colour pattern comprising a brownish dorsal surface, yellowish flanks and abdomen, and a black to bluish lateral stripe extending from the eye to the caudal-fin base.

This species can be distinguished by the following characters: juveniles with brown body and dark marking at base of caudal-fin; 37-42 + 3-4 lateral line scales; 11½ branched dorsal-fin rays; 7½ scale rows between lateral line and dorsal-fin origin; 20-25 predorsal scales; dorsal-fin relatively small with anterior branched rays shorter than head in juveniles, slightly longer than head in adults.

This species is relatively rare in the aquarium trade. It can be differentiated from all congeners by a combination of possessing ctenoid (vs. cycloid) scales on the sides of the head plus lacking a dark spot at the caudal-fin base.

Sand-dwelling loaches from the families Botiidae, Cobitidae and Nemacheilidae are also suitable but proper research is essential as some can be excessively territorial or otherwise aggressive. A community based around fishes from its natural waters could include species such as Badis badis,...

According to Kottelat (2012) L. manipurensis Arunkumar, 2000, which was described from Moreh, Manipur state, northeastern India, close to the border with Myanmar, is a syonym of L. micropogon. Havird and Page (2010) differentiate the two based on caudal-fin patterning, predorsal length and ver...

L. elongata is the type species of the genus but according to current knowledge there exist 13 members in total, all of which are endemic to China and northern Vietnam. They're diagnosable by the following shared characters: possession of a simple (non-bifurcated), short sub-ocular spine not extending beyond the posterior edge of the eye; a laterally-compressed body; relatively deep caudal peduncle; pelvic fins reaching origin of anal-fin; anus below base of dorsal-fin and equidistant between pelvic and anal-fin origins.

This species is poorly known in general and is not present in the ornamental trade, although its name is widely misapplied to other Luciosoma species. Its congeners are mostly marketed as 'apollo shark', 'shark minnow', or similar, and often labelled with incorrect scientific names. Identification of the fish pictured here is based on Bleeker (1855, 1860) and Roberts (1989), plus drawings by Bleeker, thus...

The genus Mchenga was erected in 2006 by Stauffer and Konings and currently numbers half a dozen species, all of which are previous members of Copadichromis. The reclassification was based on various morphological and behavioural traits, including habitat preference and breeding strategy. Together with Copadichromis, Mchenga spp. form an exclusive group of Malawian cichlids commonly referred to as "Utaka" (prounounced "ooh-taw-kuh"). They're specialised to a pelagic l...

This species was previously referred to as M. thoracata, but that name is now applied to the species with a relatively short dorsal-fin spine which was formerly known as M. personata. M. picta can be told apart from M. thoracata by presence of a dark vertical bar in the caudal-fin, a comparatively longer dorsal-fin spine (52.0-64.0% vs. 32.0-48.0% of dorsal-fin base in specimens measur...

This species is also known as 'Marilyn's pencilfish'. It's rarely traded in numbers and more often seen as bycatch among shipments of other species, particularly Paracheirodon axelrodi. It can be identified by the following combination of characters: three dark lateral stripes (sometimes referred to as primary, secondary, and tertiary); nocturnal oblique bars relatively narrow, with the anterior bar reaching, but not extending past, the anterior base of the dorsal-fi...

Ther are currently five described species of Nemadoras (N. elongatus, N. hemipeltis, N. humeralis, N. leporhinus and N. trimaculatus). All are rare in the hobby, although this species is the one most commonly seen. As well as the occasional import, it sometimes shows up as bycatch among batches of similar-looking Hassar or Hemidoras species. Of these, it is most often confused with Hemidoras stenopeltis. These two can be easily told apart as N. leporhinus has a clearwith a dark patch at the base...

Nematabramis species are found a variety of habitat-types, from swiftly-flowing affluent streams to pools, lakes, and degraded swamps. Based on the available collection records juveniles and subadults of N. everetti display a preference for fast-moving water whereas adults are found in deeper, slower stretches of minor tributaries.

Several geographical morphs of this species are available, including "Sambia" and "Kipili". These vary in base colour from blue to yellow to white. It is not recommended for the general Tanganyikan community due to its aggressive and predatory nature....

This species occasionally appears in the ornamental trade, usually as 'striped hill trout' or 'banded hill trout'. It can be distinguished from congeners by the following combination of characters: lateral line complete with 40-42 scales; barbels absent; 10-13 anal-fin rays; body with 9-11 dark blue vertical bars; last dorsal-fin ray extending to caudal-fin base.

O. dogarsinghi and O. bernatziki are the only two Southeast Asian congeners to possess a large blotch at the caudal-fin base but in the former the blotch is vertically-orientated and hardly extends onto the fin itself (vs. laterally-elongate and extending onto the basal fin rays) and long (vs. short) barbels, while th...
