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).

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.

Barilius gatensis (VALENCIENNES, 1844)

Malabar Baril

October 5th, 2012 — 10:42am

This species is traded very occasionally, sometimes under the alternative vernacular names of ‘river baril, ‘river carp-baril’, or ‘striated hill trout’.

It can be told apart from congeners by the following combination of characters: 1 pair of minute rostra…

Mesonoemacheilus petrubanarescui (MENON, 1984)

May 23rd, 2012 — 1:41pm

Type locality is ‘Netravati River, Dharmasthala, Karnataka State, India’, with the species subsequently recorded from the Kabini (aka Kabani) River basin and it may be endemic to these two drainages.

While the Netraviti flows through Karnataka in its entirety before emptying into the Arabian Sea just south of the city of Mangalore, th…

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.
