Ctenopharyngodon idella (VALENCIENNES, 1844)

Grass Carp

September 30th, 2014 — 12:57pm

Despite being a wholly unsuitable aquarium subject, C. idella is often traded as such, with an albino form having been developed specifically for the ornamental market.

Individuals which have outgrown their aquarium or pond should never be released into natural waters, either, since this species has proven capable of causing serious environmental damage under a wide range of climatic conditions.

Devario assamensis (BARMAN, 1984)

November 29th, 2012 — 12:28pm

Type locality is ‘Streamlets near Tangla, Darrang District, Assam, India’, but records also exist from the Mahananda River in West Bengal state and other tributaries of the lower Brahmaputra river system, some of which originate in Bhutan.

Further upstream it’s been recorded in the Kalmoni riv…

Barilius bendelisis (HAMILTON, 1807)

October 3rd, 2012 — 4:17pm

Type locality is given as ‘Cedaw√°ti [Vedawati] stream, headwaters of Krishna River near Heriuru, Mysore, India’, with the species currently considered to occur throughout India, Bangladesh, Nepal, and probably Bhutan.

It’s also been recorded in Pakistan, Myanmar, Thailand and Sri Lanka although some or all of these reports may refer to other species.

Opsarius barna (HAMILTON, 1822)

October 3rd, 2012 — 1:19pm

This species occasionally appears in the ornamental trade, usually as ‘striped hill trout’ or ‘banded hill trout’.

It can be distinguished from congeners by the following combination of characters: lateral line complete with 40-42 scales; barbels absent; 10-13 anal-fin rays; body with 9-11 dark blue vertical bars; last dorsal-fin ray extending to caudal-fin base.

Puntius chola (HAMILTON, 1822)

Swamp Barb

September 28th, 2012 — 4:23pm

P. chola was retained in Puntius sensu stricto, of which members are defined by the following combination of characters: adult size usually less than 120 mm SL; maxillary barbels absent or present; rostral barbels absent; 3-4 unbranched and 8 branched dorsal-fin rays; 3 unbranched and 5 branched anal-fin rays; last unbranched dorsal-fin ray weak or strong and unserrated; lateral line complete with 22-28 pored body scales…

Paracanthocobitis botia (HAMILTON, 1822)

Zipper Loach

March 13th, 2012 — 1:22pm

Traded under various names including ‘mottled’, ‘eyepot’, ‘sand’ and ‘striped’ loach. It’s perhaps one of the better choices for those new to keeping nemacheilids being relatively hardy, peaceful and exhibiting some quirky behavioural traits. The characteristic ocellus, a dark marking at the top of the caudal peduncle that resembles an eye, is thought to have some function in predator distraction and is normally more intense in younger specimens.

Botia dario (HAMILTON, 1822)

Bengal Loach

March 13th, 2012 — 1:20pm

Following Grant (2007) this species is included in the B. dario complex of closely-related species within the genus alongside B. striata. They're characterised by body patterning consisting of a base yellow to golden colour with 7-9 blue, green, grey or black body bars usually with thinner, lighter bars between. In some individuals the…

Pethia ticto (HAMILTON, 1822)

Ticto Barb

March 13th, 2012 — 1:19pm

Apparently most abundant in shallow streams and minor tributaries, sometimes at relatively high altitudes, and apparently shows a preference for substrates of mud or silt. Given the extent of its range it would seem sensible to assume that it inhabits various habitat-types which also vary in water depth, flow, and turbidity depending on the time of year.

Anabas testudineus (BLOCH, 1792)

Climbing Perch

March 13th, 2012 — 1:18pm

This species isn't especially popular in the aquarium trade but is undoubtedly interesting despite its lack of colour. In addition to its survival ability in the absence of water it's also capable of producing audible sounds though the purpose of these has not been fully-studied. Naturally-occurring xanthic and albino forms have also been recorded.

There is considerable confusion as to the taxonomic status of the two species currently occupying this genus, with ichthyologists widely…
