Tanichthys sp. 'Vietnam'

September 14th, 2012 — 9:30am

This fish was first collected in 2009 and limited numbers have been available in the aquarium trade. Though additional exports may be unlikely it’s proven easy to breed in captivity and there’s a fair chance it will become established in the hobby. It’s sold under several names including T. sp. ‘lemon’ or ‘yellow white cloud’, and has also been misidentified as the congener T. thacbaensis, a valid species occurring much further north in Vietnam.

Garra sp. 'redtail'

Burmese Red-tailed Garra

March 13th, 2012 — 1:24pm

A putatively undescribed species often imported and sold as G. sp. ‘burmanicus’. It first appeared in the trade during 2005 and has since been available on a sporadic basis, usually with a relatively high price tag. As well as its unique colour pattern, a primary diagnostic character is the presence of a proboscis-like rostral process between the eyes.

False SAE

March 13th, 2012 — 1:24pm

Also known by the vernacular names ”black band garra’, ‘stone-lapping minnow’ or ‘false flying fox’ and continues to be traded as Garra taeniata, an invalid name synonymous with G. cambodgiensis.

It is often confused with those laterally-striped members of the genus Crossocheilus sold as ‘Siamese algae eater’ or ‘Siamese flying fox’, but in those species the dark lateral body stripe continues into the caudal-fin whereas in G. cambodgiensis it terminates…

Rhino Garra

March 13th, 2012 — 1:24pm

The preciose function of the secondary rostrum remains unknown; some have suggested it may have some hydro-mechanical purpose but it’s perhaps more likely related to reproductiion and/or social interactions. Only males develop prominent rostra…

The type locality is located in a hilly area mostly comprising bamboo forest. At time of collection the water was clear, colourless and flowing at a moderate pace over a substrate of rocks and gravel. It was 1-2 metres wide and maximum depth was only 0.5 metres.

Due to the surrounding forest some stretches were shaded and others more open. Sympatric species included…
