This species was referred to as Dario sp. ‘Jaintia Hills’ or D. sp. ‘Bangladesh’ prior to its description. Type locality is 'India, Meghalaya, Jaintia Hills, Seinphoh stream at Umolong, 7 km from Jowai town, 25°31’36’’N 92°08’27’’E, 1320 m asl', and in India it has not been found elsewhere to date.

This species has not yet entered the aquarium trade but is maintained by a handful of private collectors. Though described in 2012 it was in fact first collected in the latter half of the 19th century with Day (1875-1878) having mentioned the presence of Badis dario in ‘Wynaad’ and its occurrence "along the Western Ghats" (the chain of mountains in southwestern India).

In aquarium literature this species is also referred to as 'fine scaled tiger fish', 'Indonesian tiger fish', 'Sumatran tiger fish', 'Indo datnoid', and 'Indo dat'. The common name of 'tiger fish' is also used in reference to the African alestid genus Hydrocynus, and the more appropriate 'tiger perch' was suggested by Roberts and Kottelat (1994).

D. assimilis has been misidentified as Puntius mahecola (Valenciennes 1844) in the past but the identity of both species was resolved by Pethioyagoda and Kottelat (2005 a, 2005b). They inspected the syntypes of P. mahecola and concluded that though valid it isn't closely related to any Dawkinsia (then the Puntius filamentosus group) but is rather a smaller, silvery fish with a single dark blotch on the caudal peduncle, located entirely posterior to the anal-fin. It's wi....

Known only from Kanyakumari District, Tamil Nadu state, at the southern tip of the Indian peninsula. Type locality is the Kodayar River drainage and it's also been collected in the Paralayar and Pamburivaikal river systems. No precise data is available but it's certainly a pelagic, riverine species with habitats likely to vary depending on locality and time o...

This species may have appeared in the aquarium trade under the misapplied names Puntius arulius or P. tambraparniei in the past, both of which are also now classified within Dawkinsia. See the relevant profiles for D. arulius and D. tambraparniei for additional information regarding that confusion, since here we concentrate on D. rubrotinctus. It was initially described by Jerdon in 1849 but placed in synonymy with P. arulius by Day (1878), where it remained for ov...

Probably a micropredator feeding on small insects, worms, crustaceans and other zooplankton in nature. In the aquarium it will accept dried foods of a suitable size but should not be fed these exclusively. Daily meals of small live and frozen fare such as Daphnia, Artemia, and suchlike will result in the best colouration and encourage the fish to come into breeding condition. It's a schooling species by natur...

The type series was purchased from a market in Jambi province, eastern Sumatra, Indonesia and this species is also known from neighbouring Riau province plus the island province of Bangka. On Sumatra it may be restricted to the Indragiri and Batang Hari river systems. Inhabits peat swamp forests and associated black water streams in which the water is typically stained brown with humic acids and other chemicals released by decaying organic material. The dissolved mineral content is generally negligible and the pH can be as...

This species is rare in the aquarium trade with the majority of fish available under the name or the vernacular 'pentazona barb' being the closely-related D. hexazona. The two are almost identical in terms of both appearance and meristics but can be separated by the fact that D. pentazona possesses a small dark marking at the posterior base of the dorsal-fin which is absent in D. hexazona.

This species is one of three similar-looking members of the genus alongside D. johorensis and D. trifasciatus, while it may also be confused with Striuntius lineatus. Juveniles of all except S. lineatus exhibit a vertically-barred rather than laterally-striped colour pattern, the metamorphosis to adult patterning beginning at around 20 mm SL and normally being complete by 30-40 mm.

Type locality is 'Tenasserim, Myanmar' which at time of description was used to refer to the portion of Myanmar lying to the south and east of the Ayeyarwaddy/Irrawaddy river delta, including present-day Kayah, Kayin, and Mon states, Bago Division, and possibly the southern Tanintharyi Region. Blyth's description paper covered fishes collected from the Sittaung River (plus a few Gangetic species) in what is currently Bago Division, but we've been unable to locate any modern records of D. affinis fro...

This species is poorly known and first appeared in the hobby during 2005 but has rarely been seen since, probably because its natural waters lie outside the range of most commercial collectors. It can be distinguished by a combination of characters including: lateral line complete; infraorbital process absent; two pairs of short barbels; 8-9 branched dorsal fin rays; 12-13 branched anal fin rays; P stripe originating above pelvic fin and extending to en...

Ecological studies have revealed this species to be more of a generalist than its chiefly insectivorous congeners. Aquatic and terrestrial insects form a significant proportion of the diet, but substantial amounts of filamentous algae and diatoms are consumed with water mites, fish scales, isopods, nematodes and detritus also taken occasionally. In the aquarium it's largely unfu...

This species is diagnosable from other members of the genus primarily by its unique colour pattern which consists of 7-11 dark blue, irregularly-shaped, parallel vertical bars on the anterior portion of each flank plus a short horizontal stripe on the caudal peduncle which extends into the central caudal fin rays. Phylogenetic analyses suggest it's most closely-related to Indian Devario spp. plus D. xyrops from the western slope of the Rakhine Yoma mountains in Myanmar (Fang et al., 2009; Fang and Kullander, 2009).

This unidentified species was first collected in 2007 but very little is known about it. The vernacular name refers to the colour pattern on the body which resembles that of a giraffe, and it's known to be collected in Myanmar although its distribution and natural habitat remain a mystery.

This unidentified species has only appeared in the aquarium trade on a handful of occasions and it has been widely misidentified as Devario jayarami (Barman, 1984). It differs from D. jayarami by possessing 9-10 lateral bars which progressively increase in size posteriorly (vs. 12-13 bars which decrease in size posteriorly), 12 anal-fin rays (vs. 15-16) and a blunter head profile with a lack of convexity behind the head (vs. head profile conical with noticeable convexity behind the head).

A good choice for the larger community tank. Newly imported fish tend to be a little delicate and can be susceptible to disease. This is at least in part because all specimens sold for the trade are wild caught. Once acclimatised it usually proves very hardy and adaptable....

Dicrossus Filamentosa were once part of the Crenicara genus, but now share the Dicrossus genus with Dicrossus Maculata. The two species look similar, but the Maculata lack the lyretailed of the Filamentosa. Some say however, that the Maculata has even more striking body colouration than the already impressive Filamentosa. These fish aren't impossible to find, but aren't readily available in local fish shops either. They are seen as a challenge to breed, but plenty of breeders have h...

Dicrossus Maculatus are not commonly available in the trade. Sometimes they are mistaken for the more common and popular Dicrossus Filamentosa. The Spadetailed Checkerboards are an absolutely fascinating species to keep. They are a challenge to breed, requiring such acidic and soft water, but when it does happen it is a very rewarding experience. Reports maintain that the pH and temperature of the water when conceived, eggs laid, eggs hatched and in the first month of the fry's life c...

D. compressiceps is an ambush predator in nature, its laterally compressed shape and head-down hunting position allowing it to remain hidden among Vallisneria beds and making it tricky to spot in open water. It has a dark stripe running from the snout along the back to the tail which serves to provide further camouflage. Despite its common name, it does not prey solely on the eyes of other species, preferring to hunt small fish (particularly juvenile Copadichromis sp.). It swallows these tai...
