One of four similar-looking, laterally-striped 'Puntius' spp. native to Southeastern Asia alongside 'P.' gemellus, 'P.' johorensis, and 'P.' trifasciatus. Of these 'P.' lineatus is most often confused with 'P.' johorensis by virtue of the fact that these two seem most common in the aquarium trade. Telling them apart is relatively simple since 'P.' lineatus has 0 - 1 pairs of barbels (vs. 2 pairs in the other three species), juv...

This species is very similar in appearance to S. berdmorei which is native to India and Myanmar, and has been widely mislabelled under that name in older aquarium literature. The two can appear identical on first glance but there are some notable differences, most obviously possession of 9-10 branchedrays in S. beauforti vs. 11-14 in S. bermorei, and the fact that even young specimens of S. beauforti exhibit laterally-orientated rows of small, dark markings running across the ...

This species is rarely-exported for the aquarium hobby but is available on occasion. The name 'P.' kuchingensis is frequently misapplied, however, with subadult forms of 'P.' everetti and some populations of the geographically-variable 'P.' lateristriga regularly traded as such, for example. Though closely-affiliated with and superficially very similar to...

The genus Amblypharyngodon currently contains five valid species, and A. chulabhornae can be distinguished from congeners by the following combination of characters: 42-50 (vs. 50-79) scales in the lateral row; lateral line incomplete with 6-7 (vs. 7-23) perforated scales; 4-5 scales on a transverse row between the lateral line and pelvic-fin base. All members of the genus lack barbels.

A. taurus can be told apart from congeners by the following combination of characters: infraorbitals and preopercle covered by thick skin and not visible externally (vs. covered by thin skin and externally visible in other Aspidoras); nuchal plate reduced, covered by thick skin and not visible externally (vs. well developed, covered by thin skin and visible externally); lateral line absent posterior to two small lateral line ossicles (vs. lateral line present on at least first body plate).

B. aurotaeniatus is uncommon in the aquarium trade. Following Kottelat (1998) it has a single pair of maxillary barbels, a complete lateral line and colour pattern usually comprising four small, vertically-orientated black markings on the flanks (located above anterior lateral line origin, below dorsal-fin origin, below posterior end of dorsal-fin base and on caudal peduncle, respectively) and one on the dorsal surface, below dorsal-fin origin.

B. coccina can be told apart from other members by the following combination of characters: iridescent green lateral blotch present in male, absent in female; body dark red in colour; no parallel vertical iridescent gold opercle bars; pelvic fin falcate with black filamentous tip, remainder red; median fins with discrete iridescent green spots; dorsal fin-rays 9-12; anal-fin rays 27-29; subdorsal scales 7-8; lateral scales 31-32; predorsal scales 18-21. The genus Betta is the most speciose within the family Osphronemidae with almost 70 reco...

B. persephone can be told apart from other members of the group by the following characters: no lateral blotch; body blackish; dorsal surface of head posterior to eye sloping gently; no parallel vertical iridescent gold opercle bars; pelvic-fin falcate with white filamentous tip, remainder black to reddish; median fins covered diffusely with light green iridescence; dorsal fin-rays 9; anal-fin rays 24-27; subdorsal scales 6-7; lateral scales 27-29; predorsal scales 17-18.

Populations known in the aquarium trade include 'Cuao', 'Orinoco', 'San Antonio', and 'Sipapo Ventuari'. B. wavrini and its congener B. cupido can be separated by body shape and position of the dark blotch on the posterior portion of the flank. In B. cupido the body is relatively compact and the blotch located above the upper lateral line, whereas in B. wavrini the body is noticeably elongate and the blotch on or below the upper lateral line.

Within the genus Boraras this species is most similar to B. naevus, though in the latter the red body colouration does not extend into the head. The two also differ in the following characters: anteriormost lateral blotch of comparable size in both sexes in B. maculatus vs. significantly larger in male than female B. naevus; 9-10 + 9 principal caudal-fin rays vs. 9 + 8; 26-29 lateral scales vs. 24-26; i.6.i. pelvic-fin rays vs. i.5.i.

This species is very rare in the trade and is normally imported only as bycatch among shipments of other fishes. It can be told apart from its well-known congener B. dorsiocellata by a combination of characters as follows: lateral line complete (25-30 pored scales vs. 4-9); more scales in the lateral row (29-32 vs. 25-27); larger adult siz...

Although described as a member of Corydoras this species was later moved into the genus Osteogaster by Cope (1894), but this was later synonymised with Corydoras by Gosline (1940). It is sometimes confused with C. venezuelanus, while two similar-looking, unidentified fishes from Peru have been assigned the codes CW007 and CW043, respectively.

Following Rainboth (1996) distinguishing characters for G. fuliginosa include: presence of rostral and maxillary barbels; a well-developed, trilobed rostrum; possession of 10 gill rakers on the lower portion of the first gill arch; no mid-lateral body stripe; 32-34 lateral line scales; body dark with random lighter scales in places. Kottelat (2001) states that the species can be told apart from other Garra occurring in Laos by a combination of: snout with a secondary rostrum, proboscis about twice as wide...

G. cornusaccus can be distinguished from congeners by the following combination of characters: secondary rostrum present; incomplete postoral pouch present reduced to pockets located posterior to mouth corners; sublacrymal groove present and visible when viewed laterally; juveniles with thick, cream-coloured bars and blotches on body, adults uniformly-coloured; head dorsum plain; subopercular groove absent; gill slit vertical; snout truncate when viewed dorsally; no scales on abdomen; 55-61 lateral line scale...

Following Roberts (1997) G. ariza can be diagnosed by the following combination of characters: body with variably intense thin stripes dustributed mostly above the lateral line; larger individuals sometimes with a broad midlateral stripe; 32-35 lateral scales; 7-8/1/5-6 transverse scale rows; 8-9 branched dorsal-fin rays 8-9; 22-24+ 11-12=34(4), 35 (3) vertebrae; live colour pattern variable, overall dull dirty white to greyish, silvery or yellow.

G. lobatus can be distinguished from congeners by the following combination of characters: possession of 32-33 + 2-3 lateral line scales; 5½ scale rows between lateral line and base of dorsal-fin; body relatively slender, depth fits 3.7-4.0 times in SL; snout often projecting strongly; body plain silver in colour.

This species is poorly-known in the aquarium hobby and may have never been maintained outside its native countries. It can be distinguished from congeners by the following combination of characters: 26-27 lateral line scales; two roundish, dark blotches on each flank, one beneath dorsal-fin origin and above the lateral line, the other on the caudal peduncle and passing thro...

Often confused with Hemichromis bimaculatus. These species can be easily distinguished as H. lifalili have only two black spots on the flanks whereas H. bimaculatus has three, having an extra spot on the caudal peduncle. It can also be told apart from the similar red form of H. guttatus by comparing the midlateral markings of the two. In lifalli the marking is round and is situated above the lateral line. In guttatus the marking is oval in shape and some of it extends below the lateral line. ...

The genus Hypancistrus is diagnosed from all other loricariids by a wide separation between the metapterygoid and lateral ethmoid, presence of a sharply angled adductor palatini crest of the hyomandibula, and no lateral wall in the metapterygoid channel. More useful for aquarists is the fact that in Hypancistrus the dentary teeth are about twice a...

It differs from H. paucilepis by possessing 30-31 scales in the lateral row (vs. 28-29), 3 scales between the lateral line and anal-fin (vs. 4), 10 predorsal scales (vs. 9), ii, 9 dorsal-fin rays (vs. iii, 8), 4 maxillary teeth (vs. 1), and the distance between the dorsal-fi...
