Appears to have a disjunct range with records from Pahang state in central Peninsular Malaysia, plus the Mae Klong and Chao Phraya river systems in Thailand, but it has not been recorded in Peninsular Thailand. Type locality is 'Pahang River, Kuala Tembeling, eastern slope of Sangka Dua Pass, Malaysia, elevation about 2000 feet'.

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 is the only species in the genus Erpetoichthys, and is an incredibly hardy, nocturnal species. Due to its poor vision, the Ropefish relies on its excellent sense of smell to locate food. It's closely related to the Polypterus genus and both these are some of the last surviving relatives of very ancient species. Fossils of earlier relatives have been found that date back to the Triassic Period, which occured during the early development of the dinosaurs, more than 200 million years ago....

E. sinensis was initially included in the genus Protomyzon where it remained until 2004 when Kottelat found sufficient geographical and morphological differences between members of the group inhabiting the island of Borneo and those from mainland East/South East Asia to warrant their separation. The genus Erromyzon was erected to accommodate the mainland fishes and there are currently three...

This species was available in the aquarium hobby for a number of years prior to publication of the official description and was generally referred to as A. sp. 'Namak' or A. sp. 'Namak River'. It can be distinguished from other members of the genus by the following combination of characters: 10–12 anal-fin rays; 28–32 lateral line scales, 10–13 caudal peduncle scales; 8–10 gill rakers; 12–19, commonly 1...

E. caudiocellatus can be told apart from congeners by lacking a dark lateral stripe and possessing a prominent dark marking on the caudal peduncle. In recent years a number of phylogenetic studies involving Esomus and its near relatives have been conducted and conflicting results published. For example a 2003 study by Fang et al. concluded that the genus is the sister group, i.e., most closely-related to...

This species is not a common aquarium species but is occasionally available from specialist retailers or breeders. It was initially named Adinia multifasciata by Girard (1859) before later being redescribed as Fundulus xenicus (mispelled 'Fundnlus') by Jordan and Gilbert (1882). Body stout and trapezoidal in adults, body depth usually 2 to 3 times in standard length; scales large, fewer than 30 scales along midlateral scale row...

Garra species are usually included in the subfamily Labeoninae/Cyprininae (name varies with author) which by current thinking is further divided into several tribes and subtribes (Stiassny and Getahun, 2007). The putatively monophyletic subtribe Garraina comprises Garra plus numerous other genera including the well-known Crossocheilus and Epalzeorhynchos. Within this division their closest relatives are members of Discogobio, Discocheilus and Placocheilus (the lat...

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. 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. salweenica can be distinguished from other congeners inhabiting the Salween watershed by the following combinatuion of characters: body brownish; presence of a trilobed proboscis on the snout; snout blunt; a series of black spots at the base of the central dorsal-fin rays; presence of longitudinal stripes on the posterior portion of the body; a dark marking at the tip of the upper (and lower in some specimens) caudal-fin lobe; body depth 22.4-25.3 % SL.

A putatively undescribed species often imported and sold as G. sp. 'burmanicus'. It first appeared in the trade during 2005 and has since been available on a sporadic basis, usually with a relatively high price tag. As well as its unique colour pattern, a primary diagnostic character is the presence of a proboscis-like rostral process between the eyes.

The type series was collected from a stream-like tributary of the Chalakkudy River at an altitude of 483 m AMSL. In March 1996 the habitat measured around 15 m across and comprised shallow (~ 20 cm deep) water flowing slowly through moist deciduous forest over a substrate of pebbles and boulders.

Although only described in 2006 this species has been known in the hobby since at least 1988 when it was imported to Germany and traded as G. sp. 'Parnaíba'. An undescribed species from the rio Pindaré in Maranhão state usually sold as G. sp. 'Pindaré' is sometimes labelled G. sp. 'Pindaré' (Parnaíba) which has resulted in some confusion but the two do not occur sympatrically and are totally distinct from one another.

This species was introduced into the aquarium trade in the early 20th century but disappeared soon after. It subsequently reappeared in a Berlin zoo in 1965 and has been available from specialist breeders ever since. It occasionally appears for sale in aquatic shops....

This species was originally classified in the genus Limnochromis. There are a couple of colour morphs available and these should not be mixed in aquaria, as they may hybridise. In nature, this fish feeds in a similar way to Geophagus species, in that it will sift sand through its gills to extract invertebrates hidden in the substrate. It is a deep water fish and has been recorded foraging at depths of up to 200 metres. These movements seem to be related to the presence of the plankton on which...

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.

Not a good beginner's species, due to its very respectable adult size, but it makes a stunning oddball addition to communities of larger fish. It's sensitive to many aquarium medications, particularly those containing copper. The genus Gymnotus has undergone considerable taxonomic revision in recent years, with over 20 new species being described since 1994, including several that were originally considered to be G. carapo. The systematics of the genus are still not fully understood...
