Lepidocephalichthys micropogon BLYTH, 1860

January 16th, 2013 — 11:07am

According to Kottelat (2012) L. manipurensis Arunkumar, 2000, which was described from Moreh, Manipur state, northeastern India, close to the border with Myanmar, is a syonym of L. micropogon.

Havird and Page (2010) differentiate the two based on caudal-fin patterning, predorsal length and ver…

Homalopteroides modestus (VINCIGUERRA, 1890)

January 2nd, 2013 — 2:25pm

Homalopteroides spp. are specialised micropredators feeding on small crustaceans, insect larvae and other invertebrates.

In captivity some sinking dried foods may be accepted but regular meals of live or frozen Daphnia, Artemia, bloodworm, etc., are essential for the maintenance of good health.

Schistura balteata (RENDAHL, 1948)

Sumo Loach

October 6th, 2012 — 4:25pm

This species is quite uncommon in the aquarium hobby although its name is sometimes used in reference to the similar-looking, apparently undescribed congener S. cf. balteata, and both are also traded as ‘sumo loach’, ‘tri-banded sumo loach’, and ‘orange saddle-back loach’.

Following Kottelat (1990) it’s diagnosed by the following combination of characters: unique colour pattern consisting of two da…

Pethia sp. 'Myanmar'

October 6th, 2012 — 2:21pm

This fish has been widely misidentified and sold as the congener P. tiantian and its vernacular name of ‘Burmese bumble-bee barb’ but actually appears to be an undescribed member of the genus Pethia.

This assemblage was erected by Pethiy…

Petruichthys sp. 'rosy'

Rosy Loach

September 24th, 2012 — 4:05pm

This species continues to be referred to by the fictitious scientific name ‘Tuberoschistura arakensis‘ but actually appears to be an undescribed Yunnanilus sp. and is also sometimes traded as Y. sp. ‘orange’ or ‘Burmese pink loach’ but appears to be a member of the genus Petruichthys as per Kottelat (2012).

There exist more than 30 described Yunnanilus spp., the…

Indostomus paradoxus PRASHAD & MUKERJI, 1929

Armoured Stickleback

March 13th, 2012 — 1:26pm

This species is rare in the aquarium hobby though its name is often misapplied to the closely-related I. crocodilus. It can be told apart from congeners by the following characters: dorsal and anal fins without dark markings, with a light brown bar in breeding males; ventral surface light brown; throat white, occasionally with a few brown spots; ridges of head bones weakly serrated or not serrated, depending on the bone.

The family Indostomidae currently contains just a single genus with three species of which I. paradoxus is the type. It was raised alongside both family…

Oryzias minutillus SMITH, 1945

Dwarf Medaka

March 13th, 2012 — 1:26pm

Best maintained in a heavily planted set-up, ideally with a dark substrate, patches of dense vegetation, and some open areas. Other décor can consist of twisted roots and pieces of bogwood, while surface vegetation is also appreciated by the fish. When maintained under such conditions they’re more likely to display their best colours, and planted aquaria also offer fry a more favourable chance of survival alongside the adults.

Oryzias dancena (HAMILTON, 1822)

Indian Ricefish

March 13th, 2012 — 1:26pm

This species continues to be mislabelled as O. melastigma, a name currently considered invalid by the majority of recent workers, or O. javanicus, a valid but distinct taxon. Roberts (1998) demonstrated that MClelland’s description of Aplocheilus melastigmus, later renamed O. melastigma, does not correspond with any known Oryzias species from the Indian subcontinent or Myanmar since it’s said to have a dark spot in the dorsal-fin and an excessively slim body, among other anomalies.

Pethia tiantian (KULLANDER & FANG, 2005)

March 13th, 2012 — 1:25pm

Known only from the remote, mountainous area of Putao in Kachin state, northern Myanmar. The holotype and most of the type series was collected from the Nan Hto Chaung (Nan Hto stream) with the Mali Hka River representing the only other locality known. Both are part of the upper Irrawaddy/Ayeyarwady system.

The Nan Hto Chaung flows through forested hills and…
