Hemibarbus labeo (PALLAS, 1776)

Barbel Steed

October 24th, 2014 — 5:16pm

This species can be distinguished from other members of the genus by the following combination of characters: absence of dark spots on body in adults; body elongate with slightly convex dorsal profile; head longer than body is deep; snout much longer than postorbital head length; lips well developed, lateral lobes of lower lip broad and thick with folds, median process small; barbel thickness shorter or equal to eye diameter; dorsal spine strong, ⅔ of HL; dorsal-fin origin closer to tip of snout than caudal-fin base base; 15+ gill rakers; 6½ branched anal-fin rays; posterior simple dorsal-fin rays ossified and spinous.

Hemibarbus maculatus BLEEKER, 1871

Spotted Steed

October 24th, 2014 — 12:48pm

Widepread in eastern Asia between the Yangtze and Amur river basins, including China (mainland and islands of Taiwan and Hainan), Korea, Mongolia, Russia, and Japan. It probably been introduced to Vietnam and Laos, or records from these countries represent another species.

Elopichthys bambusa (RICHARDSON, 1845)

October 18th, 2014 — 8:29pm

The adult size and power of this impressive predator preclude it from consideration as an aquarium species, but young individuals are nevertheless available in the ornamental trade on an irregular basis therefore it is included here.

It is an entirely unsuitable choice for the home aquarium and the majority of zoos and public aquaria would probably struggle to maintain it in adequate conditions.

Ctenopharyngodon idella (VALENCIENNES, 1844)

Grass Carp

September 30th, 2014 — 12:57pm

Despite being a wholly unsuitable aquarium subject, C. idella is often traded as such, with an albino form having been developed specifically for the ornamental market.

Individuals which have outgrown their aquarium or pond should never be released into natural waters, either, since this species has proven capable of causing serious environmental damage under a wide range of climatic conditions.

Acheilognathus macropterus (BLEEKER, 1871)

Giant Chinese Bitterling

June 29th, 2014 — 8:43pm

A. macropterus appears in the ornamental trade on an irregular basis and should only be considered by more experienced aquarists with sufficiently large facilities.

Given its wide geographical distribution there is a possibility that it represents a group of closely-related species, with genetic studies indicating the existence of several distinct clades.

Abbottina rivularis (BASILEWSKY, 1855)

Chinese False Gudgeon

June 24th, 2014 — 6:58pm

Native to continental China, the Korean peninsula, and southern Japan. Type locality is given only as ‘Lakes and rivers, northern China’, with the type series possibly originating from the Pai-ho River near Beijing.

It has been widely introduced and is considered invasive elsewhere, including the Mekong river basin (records from Laos and Thailand), Salween river (Myanmar), northern Japan, Taiwan, Turkmeni…

Channa argus (CANTOR, 1842)

Northern Snakehead

June 30th, 2013 — 2:28pm

This species is largely 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.

It’s currently illegal to import or own the species in the United States, United Kingdom and several other countries unless in possession of an official license.

Misgurnus dabryanus DABRY DE THIERSANT, 1872

Large-scaled Loach

March 13th, 2012 — 1:26pm

It’s actually sold in the aquarium hobby on a regular basis but almost always labelled as or mixed in with Misgurnus anguillicaudatus and is thus poorly documented.

Although quite simi…

Macropodus ocellatus CANTOR, 1842

Roundtail Paradise Fish

March 13th, 2012 — 1:18pm

M. ocellatus can be distinguished from congeners by the following combination of characters: caudal-fin rounded; eye stripe not connecting spot on posterior projection of opercle with eye; dorsal-fin rays filamentous posterior to a vertical through the posterior anal-fin rays in adults; 16-19 spinous dorsal-fin rays; 6-13 rakers on ceratobranchial of first gill arch; posterior tip or margin of body scales not darker than scales.
