Gymnostomus ariza (HAMILTON, 1807)

October 26th, 2014 — 5:31pm

Following Roberts (1997) G. ariza can be diagnosed by the following combination of characters: body with variably intense thin stripes dustributed mostly above the lateral line; larger individuals sometimes with a broad midlateral stripe; 32-35 lateral scales; 7-8/1/5-6 transverse scale rows; 8-9 branched dorsal-fin rays 8-9; 22-24+ 11-12=34(4), 35 (3) vertebrae; live colour pattern variable, overall dull dirty white to greyish, silvery or yellow.

Garra mullya (SYKES, 1839)

October 20th, 2014 — 1:55pm

This species is endemic to and widespread within peninsular India, where it has been recorded from the states of Gujrat, Madhya Pradesh, Chhattisgarh, Orissa, Jharkhand, West Bengal, Maharashtra, Andhra Pradesh, Goa, Karnataka, Tamil Nadu and Kerala.

It is thus found in numerous river systems of which some of the most important include the Tapti, Narmada, Mahanadi, Godavari, Krishna, and Cauvery.

Pseudosphromenus cupanus (CUVIER, 1831)

Spiketail Paradisefish

February 23rd, 2014 — 5:02pm

This species is most easily told apart from its only congener P. dayi by lacking (vs. possessing) two dark, irregular lateral stripes on the head and body, and a shorter caudal-fin in males.

The results of phylogenetic analyses by Rüber et al. (2006) suggest that Pseudosphromenus is most closely-related to Malpulutta in an evolutionary sense.

Bagarius yarrelli (SYKES, 1839)


February 8th, 2014 — 5:49pm

This species is clearly 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.

The grouping currently contains four species but is in urgent need of review with a number of additional taxa thought to exist and B. yarrelli possibly representing a synonym of B. bagarius.

Dario urops BRITZ, ALI & PHILIP , 2012

November 2nd, 2013 — 12:54am

This species has not yet entered the aquarium trade but is maintained by a handful of private collectors.

Though described in 2012 it was in fact first collected in the latter half of the 19th century with Day (1875-1878) having mentioned the presence of Badis dario in ‘Wynaad’ and its occurrence “along the Western Ghats” (the chain of mountains in southwestern India).

Bhavania australis (JERDON, 1849)

June 20th, 2013 — 9:50pm

An obligate dweller of shallow, fast-flowing, highly-oxygenated headwaters and minor tributaries characterised by stretches of riffles and runs broken up by pools or cascades in some cases.

Substrates are normally composed of smaller rocks, sand and gravel with jumbles of boulders, and whil…

Schistura kodaguensis (MENON, 1987)

January 15th, 2013 — 7:54pm

This species is not a well-known aquarium fish but is maintained by a number of Indian enthusiasts.

It can be told apart from related species by the following combination of characters as per Sreekantha et al. (2006): pectoral-fin rays 10; absence of black spot at base of dorsal-fin; presence of rows of spots on caudal-fin; lateral line incomplete; caudal-fin slightly emarginate; 11-14 vertical bars on the body.

Schistura denisonii (DAY, 1867)

October 7th, 2012 — 8:00pm

This species is feisty and largely unsuitable for the general community aquarium. This is not to say it must be kept alone, rather that tankmates must be selected with care and proper research.

Slow-moving or long-finned species should certainly be omitted because they’re likely to struggle with the necessary level of water movement and may end up with nipped fins.

Paracanthocobitis mooreh (SYKES, 1839)

May 16th, 2012 — 12:01pm

This species is still considered a member of the genus Nemacheilus by some sources, but it was reclassified and placed in Acanthocobitis by Grant (2008).

Acanthocobitis sinuata, generally considered a junior synonym of A. mooreh (Kottelat, 2012b), also appears distinct and differs in geographical distribution plus number of dorsal-fin rays (2-3/9-10 in A. mooreh vs. 2/8-9 in A. sinuata) and some aspects of colour pattern.

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.
