Hampala macrolepidota KUHL & VAN HASSELT, 1823

Hampala Barb

March 13th, 2012 — 1:23pm

This species is also known by the vernacular ‘jungle perch’ or ‘sidebar barb’ and should not be considered an aquarium subject in all but the most extreme circumstances since it can grow to over 2 feet in length, weigh in excess of 5 kg and is a powerful, pelagic predator. It’s also a popular sport fish with a reputation for striking hard.

Esomus metallicus AHL, 1923

Striped Flying Barb

March 13th, 2012 — 1:23pm

There currently exist a dozen described Esomus spp. alhough few are seen in the aquarium trade and none are especially popular. Most are commonplace in their native countries and also quite plainly-patterned so generally overlooked by collectors. Their most common use in some areas is actually as a feeder fish in the aquaculture of larger species. They’re characterised by greatly-enlarged pectoral fins and two pairs of barbels, of which the maxillary pair are extremely long and usually reach the pectoral fins.

Gyrinocheilus aymonieri (TIRANT, 1883)

Sucking 'Loach'

March 13th, 2012 — 1:22pm

This species is among the most well-known fishes in the aquarium trade but juveniles are typically being offered for sale with little to no information regarding temperament, eventual size, and potential age in excess of 15 years.

Wild examples are not currently traded, with all of those seen on sale produced on a commercial basis.

Hemibagrus spilopterus NG & RAINBOTH, 1999

March 13th, 2012 — 1:21pm

This species is relatively common in the aquarium trade but has been widely misidentified as the congener H. nemurus which is native to Java and may never have been exported for ornamental purposes.

Hemibagrus has been divided into a number of putative species groups which may or may not rep…

Yasuhikotakia eos (TAKI, 1972)

Sun Loach

March 13th, 2012 — 1:20pm

Y. eos isn't as commonly-traded as it once was but is still available occasionally. It's difficult to confuse with any other member of the genus due to its colour pattern consisting of yellow to reddish brown base body colour (can appear greyish in some specimens, especially post-import or when introduced to a new aquarium) with a metallic green/blue golden sheen and large darkish marking on either side of the caudal peduncle. The fins can be yellowish to reddish, and the dorsal and c…

Barbonymus schwanefeldii (BLEEKER, 1854)

Tinfoil barb

March 13th, 2012 — 1:19pm

This is one of two species traded under the vernacular name ‘tinfoil barb’, the other being the less well-known congener B. altus. Despite this it appears that B. altus is just as widely available as B. schwanefeldii and in many cases is seen on sale more regularly. Unfortunately both are usually offered at a small size (usually around 50 – 75 mm) with little to no information regarding the eventual size of the fish.

Helostoma temminkii CUVIER, 1829

Kissing Gourami

March 13th, 2012 — 1:18pm

The pinkish-white form of this species is among the most widely-traded aquarium fishes in the world but does not occur naturally and is in fact a leucistic variant bred specifically for ornamental purposes. The 'short-bodied' or 'balloon' variety also continues to be fashionable but under no circumstances do we recommend the purchase of these intentionally disfigured animals which tend to have much shorter life spans than the naturally-shaped fish. There also exists a less-po…

Channa gachua (HAMILTON, 1822)

Dwarf Snakehead

March 13th, 2012 — 1:18pm

Generally considered to have an enormous natural range extending from Iran to Taiwan and Bali, with records existing from Iran, Iraq, Afghanistan, Pakistan, Nepal, India, Sri Lanka, Bangladesh, Bhutan, China, Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia, Indonesia, and Singapore.

However there exists significant evidence to suggest that C. gachua as currently understood represents a complex of similar-looking species, and a taxonomic review of the group is clearly required.

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…

Trichopsis vittata (CUVIER, IN CUVIER & VALENCIENNES, 1831)

Croaking gourami

March 13th, 2012 — 1:18pm

The common name is derived from the ability of genus members to produce audible sounds via a specialised pectoral mechanism which is unique within the family Osphronemidae. The structure comprises modified pectoral-fin tendons and muscles which are stretched and plucked by basal elevations of two fin rays in a similar way to guitar strings via rapid beating of the fins. The pectoral-fins beat alternately, each able to generate short or long bursts of sound. These sounds are produced by both sexes, predom…
