Metzia lineata (PELLEGRIN, 1907)

November 6th, 2014 — 12:32pm

Populations from the upper Pearl River (Nanpan Jiang basin) differ in several morphological characters from those inhabiting Guangdong, Guangxi, and Guizhou Provinces, and Hainan Island. Those from Vietnam also seem to be different (Gan et al., 2009), the implication being that there may be several species currently included under the name M. lineata.

Metzia formosae (OSHIMA, 1920)

November 5th, 2014 — 8:16pm

Although it is included in the genus Metzia this grouping remains somewhat unresolved in terms of taxonomy and it may contain more than a single genetic lineage. For example, members share a number of characters with the genera Ischikauia Jordan and Snyder 1900, Hemiculterella Warpachowski 1887, and several species of Anabarilius Cockerell 1923, including a bipartite gas bladder, a non-spinous dorsal-fin ray, and a sharp ventral keel between the pelvic-fin insertion and anus.

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.

Folifer brevifilis (PETERS, 1881)

October 19th, 2014 — 1:33pm

This species is widely-distributed in the Mekong river system in Thailand, Laos, and Vietnam, Salween and Ayeyarwaddy rivers in southern China, Myanmar, and Thailand, plus various smaller basins in Vietnam and China. It has also been recorded from the islands of Hainan and Hong Kong.

Type locality is given as ‘China: sent from Hong Kong’.

Acrossocheilus parallens (NICHOLS, 1931)

August 23rd, 2014 — 4:34pm

Members of the genus are characterised by possessing a particular number of dark vertical bar on each flank, and A. parallens belongs to a group of species with five or six such bars, each of which is two scales in width. Congeners sharing this pattern include A. fasciatus, A. hemispinus (in juveniles only), A. jishouensis, A. kreyenbergii, A. paradoxus, A. spinifer, A. wenchowensis, and A. wuyiensis.

August 23rd, 2014 — 4:13pm

Recorded from Fujian, Guangdong, and Guangxi provinces in southwestern China, plus the islands of Hainan and Hong Kong.

Type locality is ‘Lian-Xian and Yang-Shan, Guangdong, China’, corresponding to the Bei River drainage.

Rhinogobius giurinus (RUTTER, 1897)

June 14th, 2013 — 11:26am

This species appears to exist in a number of different forms which exhibit differences in colour pattern, morphology, or both, and it’s currently unclear whether all of them are truly conspecific or not although to avoid confusion we list all together here.

Tanichthys albonubes LIN, 1932

White Cloud Mountain Minnow

March 13th, 2012 — 1:18pm

One of the most ubiquitous species in the hobby and several ornamental strains are available including ‘long-finned’, ‘golden’, ‘albino’, and ‘super red’, for which care is identical to that of the ‘standard’ fish.

Unfortunately the degree of inbreeding amongst farm-bred stock has resulted in a situation whereby many of the fish available today are genetically weak and prone to disease or develop physical deformities.

Barbodes semifasciolatus (GÜNTHER, 1868)

Golden Barb*

March 13th, 2012 — 1:18pm

This species is also known by the alternative names ‘green’ or ‘Chinese’ barb. The natural ‘green’ form is an infrequent find in the aquarium trade whereas the selectively-bred ‘golden’ variant is farmed in huge numbers and is among the most popular of freshwater aquarium fish.

The latter was first produced in the 1960s and is now so ubiquitous that many hobbyists are initially unaware that it is not the natural form.

Macropodus opercularis (LINNAEUS, 1758)

Paradise Fish

March 13th, 2012 — 1:18pm

M. opercularis is a classic aquarium fish, having been introduced to the hobby by a French soldier named Gerault in 1869. Of the initial 100 specimens shipped, 22 survived and were successfully bred later that same year by another Frenchman, the Parisian Pierre Carbonnier. This gives the species the distinction of being one of the very first ornamental fish imported to Europe. It is also known as ‘Chinese fighting fish’, ‘paradise gourami’, and ‘blue paradise fish’.
