Barbodes aurotaeniatus (TIRANT, 1885)

July 10th, 2012 — 4:01pm

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.

Desmopuntius endecanalis (ROBERTS, 1989)

July 2nd, 2012 — 11:49am

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…

Desmopuntius hexazona (WEBER & DE BEAUFORT, 1912)

'Pentazona' Barb

June 28th, 2012 — 1:57pm

Native to parts of southern Borneo, eastern Sumatra, Singapore, and the Malay Peninsula. In Singapore it’s considered highly-endangered and is now restricted to the Central Catchment nature reserve.

Type locality is ‘Tuluk and Gunung Sahilan, Sumatra, Indonesia’ which appears to correspond to localities within the Kampar River drainage of which the former is now known as Teluk Meranti and is o…

Desmopuntius gemellus (KOTTELAT, 1996)

June 20th, 2012 — 3:51pm

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…

Barbodes dunckeri (AHL, 1929)

Clown Barb

June 20th, 2012 — 1:16pm

Although sometimes referred to by the vernacular name ‘big spot barb’ this species is better known in the aquarium hobby as ‘clown barb’. It has been widely misidentified as the congener B. everetti, a distinct and uncommonly-traded species from Borneo and thus appears under that name in the majority of available literature.

The two are quite easy to tell apart, with B. everetti an overall les…

Desmopuntius trifasciatus (KOTTELAT, 1996)

June 19th, 2012 — 4:51pm

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.

Dawkinsia rohani (REMA DEVI, INDRA & KNIGHT, 2010)

June 18th, 2012 — 12:06pm

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…

Dawkinsia exclamatio (PETHIYAGODA & KOTTELAT, 2005)

June 17th, 2012 — 12:41pm

There is a case, however, to suggest that D. exclamatio is not actually a distinct taxon but rather a natural hybrid between D. assimilis and a D. arulius-like fish (possibly D. rubrotinctus) which occur together at its type locality in the Kallada River at Thenmalai.

The potential of hybridisation is evidenced by the somewhat intermediate colour pattern in that it possesses a (roughly) W-shaped mid-lateral blot…

Sahyadria chalakkudiensis (MENON, REMA DEVI & THOBIAS, 1999)

June 15th, 2012 — 3:33pm

S. chalakkudiensis can be told apart from S. denisonii by possession of an inferior mouth (vs. subterminal) and presence of a black marking in the dorsal-fin (vs. absence), and the scarlet body stripe being duller and terminating beneath or anterior to the dorsal-fin origin (vs. brighter and terminating beneath the centre of the dorsal-fin).

Barbonymus gonionotus (BLEEKER, 1849)

April 17th, 2012 — 12:51pm

The genus Barbonymus was erected by Kottelat in 1999 and contains former members of Barbodes from southeast Asia. The type species is B. schwanenfeldii and currently there exist only three other representatives; B. altus, B. collingwoodii and B. gonionotus.

The latter two are rare in the hobby although an SF member has kept B. gonionotus in the past so they are worth looking out for if you harbour an…
