Betta raja TAN & NG, 2005

March 13th, 2012 — 1:24pm

It should be noted that not all authors consider the B. pugnax group to contain the same species, with some placed in the B. picta complex by Schindler and Schmidt (2006), for example.

B. raja can be told apart from other members of the B. pugnax group by the following characters: mature males with very long pelvic fins covering 15-23 anal-fin rays or even longer than the base of the anal-fin in some cases; anal-fin and lower caudal-fin with black marginal bands; 25-28 anal-fin rays; 30-32 lat…

Desmopuntius johorensis (DUNCKER, 1904)

Striped Barb

March 13th, 2012 — 1:23pm

D. johorensis can be distinguished by the following combination of characters: 5-6 dark, lateral stripes on body in specimens larger than 40 mm; stripes immediately above and below the central stripe (stripes ‘+1’ and ‘-1’, respectively) located on scale rows +2 and -2, not touching dorsal and ventral midlines (except in some small specimens from Peninsular Malaysia); stripes broad, typically between 0.5-1 scale rows deep…

Phalacronotus apogon (BLEEKER, 1851)

March 13th, 2012 — 1:22pm

P. apogon has formerly been placed within the genera Kryptopterus, Micronema (Rainboth, 1996) and more recently Phalacronotus (Ferraris, 2007) and is an important food fish across much of its native range.

It’s very similar to P. micronema but can be told apart by its longer head (HL fits 4.6± 5.3 times in…

Kryptopterus cryptopterus (BLEEKER, 1851)

Blue Sheatfish

March 13th, 2012 — 1:22pm

Known from the Malay Peninsula and Singapore plus Greater Sunda Islands of Sumatra, Borneo and Java in Indonesia with populati0ns from Thailand, Cambodia, Laos and Vietnam formerly considered as conspecific now referred to K. geminus (Ng, 2003).

Type locality is given as ‘Bandjarmassing’ which corresponds to a town now more commonly referred to as ‘Banjarmasin’ in South Kalimantan (Kalimantan Selatan) province, Indonesia (Borneo).

Chromobotia macracanthus (BLEEKER, 1852)

Clown Loach

March 13th, 2012 — 1:20pm

This species is arguably one of the most misunderstood in the hobby since it's wholly unsuitable for smaller aquaria despite its ubiquitous availability. Most retailers sell it without providing what should be considered essential information regarding long-term care and most specimens undoubtedly fail to reach their potential in captivity. The purchase of a group is also a considerable investment given that if properly cared for typical life span is in excess…

Epalzeorhynchos kalopterum (BLEEKER, 1850)

Flying Fox

March 13th, 2012 — 1:19pm

Confusion with similar-looking fishes from other genera, such as Garra cambodgiensis, laterally-striped Crossocheilus spp. or Gyrinocheilus aymonieri is not uncommon, and are largely attributable to the use of trade names such as ‘false flying fox’ or ‘Siamese flying fox’. When compared with the other species E. kalopterus exhibits several unique characters but perhaps the simplest way to identify it is by the characteristic white-edged, red and black coloured fins and the presence of two pairs of barbels.

Barbodes lateristriga (VALENCIENNES, 1842)

Spanner Barb

March 13th, 2012 — 1:19pm

This species is commonly-referred to as ‘T-barb’ in some countries. It’s closely-affiliated with and sometimes traded as the congener B. kuchingensis but that species can be told apart by colour pattern comprising a prominent row of dark spots along the lateral line, plus a short, horizontally-orientated streak extending from the upper part of the operculum. In B. lateristriga the lateral markings usually form a solid stripe and there is no streak extending from the operculum.

Brevibora cheeya LIAO & TAN, 2011

March 13th, 2012 — 1:18pm

This species is very rare in the trade and is normally imported only as bycatch among shipments of other fishes.

It can be told apart from its well-known congener B. dorsiocellata by a combination of characters as follows: lateral line complete (25-30 pored scales vs. 4-9); more scales in the lateral row (29-32 vs. 25-27); larger adult siz…

Puntigrus tetrazona (BLEEKER, 1855)

Tiger Barb

March 13th, 2012 — 1:18pm

P. tetrazona is traditionally considered to be among the most ubiquitous species available in the aquarium trade. Wild examples are rarely traded, however, and there exists ongoing confusion as to the identity of the commercially-produced ‘aquarium’ tiger barb.

A number of selectively-bred, ornamental strains are available. The albino, ‘green’ (aka ‘moss’), and ‘golden’ (leucistic) variants are particularly pop…

Channa micropeltes (CUVIER, 1831)

Giant Snakehead

March 13th, 2012 — 1:18pm

C. micropeltes is also referred to as ‘Indonesian’, ‘red’, or ‘redline’ snakehead, the latter names in reference to the appearance of juveniles which often appear in the ornamental trade despite its unsuitability for home aquaria. It is somewhat hyperbolised in the media as a fearsome, invasive “monster” fish with a reputation for killing more fish than it can eat, and even the occasional human, although in reality…
