Kryptopterus palembangensis (BLEEKER, 1852)

April 5th, 2013 — 9:05am

This species is almost unheard of in the aquarium trade though may occasionally be exported among shipments of wild fishes from Sumatra.

It’s closely-related to K. bichirris but is told apart by presence (vs. absence) of a prominent, dark lateral stripe on each flank.

Kryptopterus species are found only in Southeast Asia and the genus has been consi…

Kryptopterus limpok (BLEEKER, 1852)

April 4th, 2013 — 4:10pm

Type locality is ‘Palembang, Sumatra, Indonesia’, but this species is widely-distributed throughout much of Southeast Asia including major river systems in Thailand, Laos, Cambodia, Vietnam and Peninsular Malaysia plus the Greater Sunda Islands of Sumatra, Borneo and Java.

It’s been extensively recorded from the Mekong, Cha…

Kryptopterus bicirrhis (VALENCIENNES, 1840)

April 4th, 2013 — 10:49am

Generally peaceful though it may predate on smaller fishes and is somewhat timid so does not compete well with much larger, robust or otherwise boisterous species.

Peaceful, comparably-sized cyprinids, loaches and other catfishes perhaps constitute the best options but be sure to research your choices thoroughly prior to purchase.

Homalopterula gymnogaster (BLEEKER, 1853)

December 20th, 2012 — 4:59pm

Type locality is given as ‘Lake Meninju, Sumatra, Indonesia’, currently known as Danau (lake) Maninjau, but conceivably the fish may have been obtained from the outflowing Antokan river rather on its western side than the lake itself.

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…

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…

Vaillantella maassi WEBER & DE BEAUFORT, 1912

Fork-tailed Loach

March 13th, 2012 — 1:26pm

This species is traded under various names including 'chocolate scissor-tailed loach', chocolate long-finned loach', 'red line cobra loach', 'spiny eel loach' and 'dragon loach'. It's apparently difficult to find in its natural habitats and thus time-consuming to collect, meaning it's rarely traded in numbers, sought after by enthusiasts and tends to carry a relatively high price tag when available.

The genus currently contains just three…

Pangio semicincta (FRASER-BRUNNER, 1940)

'Kuhli' Loach

March 13th, 2012 — 1:25pm

This species is among the most frequently-misidentified in the hobby, almost always being traded as P. kuhlii. However the latter is currently considered endemic to Java, from where commercial collections are almost unheard of, and has possibly never been seen in aquaria.

Pangio shelfordii (POPTA, 1903)

March 13th, 2012 — 1:25pm

Patterning is highly variable depending both within and between populations and the species may comprise an assemblage containing a number of taxa (Kottelat and Lim, 1993; Tan and Kottelat, 2009). For example, those from Singapore and Johor possessing intricate mottling on the dorsal surface while individuals from Terengganu have a series of saddle-like markings either alternating or connecting with the midlateral markings.
