Following the key of Romand (1992) this species can be told apart from congeners by the following combination of characters: adult size > 40 mm SL; large, dark, transverse bars and some reddish-brown pigmentation on flanks; longitudinal bands more-or-less defined; longitudinal bands composed of small red spots; caudal-fin subquadrangular caudal fin; 11-13 anal-fin rays; 16-17 dorsal-fin rays; 7-8 anal-fin rays located anterior to dorsal-fin origin.

This fish remains in need of identification, and we've chosen to list unidentified members of the genus using an 'ER' numbering system in the absence of definitive information. It's quite easy to distinguish from congeners since it's the only species known to possess a colour pattern comprising a dark base colour and series of thin, paler vertical bars on the body and similarly-coloured spots on the head.

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...

This species can be distinguished from congeners inhabiting the Red River basin in Yunnan province, China, by the following combination of characters: no barbels; 46-52 lateral line scales; 16 circumpeduncular scales; pharyngeal teeth in 3 rows, 2.4.5-5.4.2; snout rounded, no secondary rostrum, no longitudinal...

G. kalpangi is distinguished from other Garra species from the Himalayan foothills by the following combination of characters: two pairs of barbels; a weakly developed proboscis represented by a squarish area anterior to the nostrils; 16 circ...

G. rakhinica can be distinguished from other members of the genus by the following combination of characters: rostral furrow shallow and snout tip smoothly rounded; rostral lobe present, proboscis absent; scaled predorsal region, chest, and abdomen; two pairs of barbels; 28 lateral line scales; 16 circumpeduncular scale rows; colour pattern almost uniform greyish on body and caudal-fin; a dark spot immediately posterior to the upper extremity of the...

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...

Known only from headwaters of the Sungai (river) Amandit, a tributary of the larger Barito basin in the Meratus mountain range, Kalimantan Selatan (South Kalimantan) province, Indonesian Borneo. There currently exist 36 officially-described members of the genus, all of which are endemic to the island with over half restricted to a single river basin or sub-basin.

This species is generally rare in the aquarium hobby though oddly appears to be one of the commoner species in Australia where it's often referred to by the vernacular name 'black-throated eartheater'. 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; no vertical bars on the flanks even when stressed/preserved; base of filaments on the first gill arch mostly covered by a flap of skin; exposed part of bra...

In a study conducted on the Arataye River, the main tributary of the Approuage, this species was mostly collected from stretches of rapids with rocky substrate which were reduced to a series of pools during the dry season. Other fishes observed at the same site were Auchenipterus nuchalis, Hypostomus gymnorhynchus and Moenkhausia cf. intermedia while at other localities in the river Bryconops affinis, Myleus ternetzi, M. rhomboidalis, Moenkhausia aff. barbouri, Curimata sp. and Serrasalmus sp. were collected.

This species is rare in the hobby though it's name is often attached to shipments of other Geophagus species. 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: possession of dark preopercular marking; no vertical bars on the flanks; relatively large, roughly oblong-shaped dark midlateral marking; caudal fin brownish with 3-5 light stripes on upper lobe and less well-defined stripes or mottled pattern of light spots with narrow dark interspaces on lower lobe.

Lake Wanam has been the subject of a management project co-ordinated by famous aquarist Heiko Bleher, who became concerned by an apparent drop in numbers of both this species and the barred rainbowfish (Chilatherina fasciata), which is also found in the lake. The drop in numbers is thought to be a result of the introduction of non-native Tilapia, Gambusia and carp species into the lake, along with a significant increase in the number of humans living in the area. G. wanamensis is now considered ...

G. ornatapinnis can be distinguished from congeners by the following combination of characters: head small; snout relatively short and blunt; caudal peduncle very deep; pectoral, pelvic, and anal fins usually reddish-orange or rose-tinted; pelvic and anal fins often with white tips; barbels completely absent.

Like many cichlids, members of the genus Herichthys share something of a confused taxonomic past. Erected in 1854 with H. cyanoguttatus the type species, its members were moved into Cichlasoma by Regan in 1905. However following a reclassification of Cichlasoma by Kullander in 1983 it was once again deemed valid. In 1996 Kullander suggested Herichthys should only contain species "sharing a colour pattern of short vertical bars or black spots posteriorly from the middle of the side, and a un...

Like many cichlids, members of the genus Herichthys share something of a confused taxonomic past. Erected in 1854 with H. cyanoguttatus the type species, its members were moved into Cichlasoma by Regan in 1905. However following a review of Cichlasoma by Kullander in 1983 it was once again deemed valid. In 1996 Kullander suggested Herichthys should only contain species "sharing a colour pattern of short vertical bars or black spots posteriorly from the middle of the side, and a unique breed...

The genus Homalopteroides was revalidated by Randall and Page (2012) and is told apart from the related Homaloptera by the following character combination: dorsal-fin origin above pelvic-fin; ≤ 60 lateral-line scales; ≤ 30 predorsal scales; oral morphology consisting of two thin and widely separated rostral barbels on each side of the mouth, thin crescent-shaped lips, the absence of any structure such as a mental pad or lobes between the lateral portions of the lower lip, and a chin that extends anterior to the lateral portions of the lower lip.

Tan (2009) redescribed H. stephensoni and it possesses the following unique character set: sub-inferior mouth with thin barbels; five principle, 12-13 secondary pectoral fin rays (usually 12); scaleless belly; pattern of keeled scales on anterior, dorsal portion of body consisting of a single central keel in the posterior third of each scale; 43-50 lateral line...

Described from Kota Tinggi district, Johor state, Peninsular Malaysia but since recorded throughout much of the country as well as parts of the the Mekong river system in Thailand, Laos, Cambodia and Vietnam plus the Kapuas and several other river basins in Kalimantan Barat (West Kalimantan) province, Indonesian Borneo. In the Kahang River, part of the Endau drainage in Jo...

The genus is monotypic and distinguished from other cyprinid taxa by a combination of a moderately compressed, elongated body with two rows of teeth on the lower pharyngeal (throat) bone and lacking barbles, visible lateral line and a symphyseal knob on the lower jaw (Talwar & Jhingran, 1991). Its small adult size evolved via a process known as miniaturisation characterised by sexually mature adults with a significantly reduced size of less than 20 mm SL. Among bony fishes cyprinids are one of the few groups in which this phenomenon occurs repeatedly...

This species may be referred to using a variety of names including 'scomb', 'sabre tooth tetra', 'sabre tusk barracuda', 'dog tooth characin, 'vampire fish', 'Cachorra' or Pirandirá (the latter two names being used in Brazil where they're also applied to congeners). It's regularly confused with the payara, H. armatus, though that species grows considerably larger, is pop...
