Sundasalanx microps ROBERTS, 1981

June 24th, 2014 — 5:11pm

The genus Sundasalanx is distributed throughout much of Southeast Asia and currently comprises seven species which have primarily been distinguished on the basis of oral and dental morphology, gill rakers and eye size. S. microps possesses 0-3 small conical teeth on ceratobranchial 5, 0-2 minute gill rakers on the first arch and a small eye measuring less…

Chitala lopis (BLEEKER, 1851)

Giant Featherback

May 17th, 2014 — 2:51pm

This species is not collected for the aquarium trade at time of writing.

In contrast to other members of the genus older juvenile and adult individuals lack dark markings on the body while the jaw is more pronounced.

Bagarius yarrelli (SYKES, 1839)


February 8th, 2014 — 5:49pm

This species is clearly unsuitable for the home aquarium given its eventual size and natural behaviour, and we know of only a handful of private aquarists with the facilities required to house it long-term.

The grouping currently contains four species but is in urgent need of review with a number of additional taxa thought to exist and B. yarrelli possibly representing a synonym of B. bagarius.

Channa melasoma (BLEEKER, 1851)

Black Snakehead

January 2nd, 2014 — 7:34pm

This species can be told apart from the similar-looking congener C. baramensis (once considered synonymous with C. melasoma) by absence (vs. presence) of a black spot in the centre of numerous body scales and absence (vs. presence in specimens larger than 120 mm SL) of a barred caudal-fin pattern.

Channa marulioides (BLEEKER, 1851)

Emperor Snakehead

January 1st, 2014 — 5:31pm

This species is often confused with the nominal congeners C. marulius (Hamilton, 1822) and C. melanoptera (Bleeker, 1855) with all three presenting taxonomic problems.

For example, C. marulioides exhibits a number of variations in colour pattern depending on collection locality with the most common possessing a brownish base colour with a series of dark, chevron-like markings along each flank and some scales margined posteriorly in white.

Channa lucius (CUVIER, 1831)

Forest Snakehead

July 10th, 2013 — 4:05pm

Prefers a dimly-lit aquarium with plenty of cover in the form of live plants, driftwood branches, terracotta pipes, plant pots, etc., arranged to form a network of nooks, crannies, and shaded spots.

Surface vegetation such as Ceratopteris spp. is also appreciated and makes the fish less inclined to conceal themselves.

Channa baramensis (STEINDACHNER, 1901)

Baram Snakehead

June 30th, 2013 — 3:24pm

This species was considered a synonym of Channa melasoma for a number of years prior to its revalidation by Ng. et al. (1996).

Specimens larger than around 120 mm SL can be distinguished by possession of a black spot in the centre of numerous body scales and a barred caudal-fin pattern, characters which are missing in both C. melasoma and the similar-looking C. cyanospilos.

Gymnochanda filamentosa FRASER-BRUNNER, 1955

June 15th, 2013 — 3:51pm

G. filamentosa has appeared in the ornamental trade but is evidently delicate and therefore recommended only to experienced aquarists.

It can be told apart from congeners by the following combination of characters: possession of filamentous dorsal and anal-fin rays in males; body transparent to translucent yellowish-brown colour in life; absence of a highly-extended second anal-fin spine; absence of carmine-red pigmentation in the dorsal, anal an…

Xenentodon canciloides (BLEEKER, 1854)

May 30th, 2013 — 11:00am

This species is a near-exclusive inhabitant of the upper water column and appreciates surface cover in the form of floating or overhanging vegetation.

Other décor is relatively unimportant but can consist of a sandy substrate with leaf litter plus some large driftwood branches and twisted roots.

Plants which can grow rooted in sand can al…

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…
