Chindwin

This species is among the few members of the family to be exported for the aquarium hobby though is by no means common. It can be differentiated from a...

At least two similar-looking fishes have been available in the aquarium trade; one, usually referred to as 'Danio sp redfin', resembles the striped form of B. kyathit but is a smaller fish and the red pigmentation in the fins is comparatively more intense. The other is also striped with red fins but grows larger; it's usually labelled as 'Danio sp. KP01' or 'Burmese zebra danio'. It remains unclear whether these are regional variants of B. kyathit or undescribed species.

Generally considered to have an enormous natural range extending from Iran to Taiwan and Bali, with records existing from Iran, Iraq, Afghanistan, Pakistan, Nepal, India, Sri Lanka, Bangladesh, Bhutan, China, Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia, Indonesia, and Singapore. However there exists significant evidence to suggest that C. gachua as currently understood represents a complex of similar-looking species, and a taxonomic review of the group is clearly required.

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...

Described from 'Etok stream near Chanderkhong, southern watershed of the Naga Hills, Manipur, Assam', located within the Chindwin River basin in northern India. The Chindwin is the major tributary of the Ayeyarwady/Irrawaddy River and most of it flows within Myanmar although two of its own tributaries, the Manipur and Yu rivers, originate in the Indian states of Manipur and Nagaland.

According to Kottelat (1990) the chief distinguishing characters for the genus are: possession of 9-18½ branched dorsal-fin rays; colour pattern without black basal caudal bar, but with an ocellus at upper base of caudal-fin; upper lip with or without several rows of papillae; lower lip with a broad median interruption and a widened, papillated pad on each side.

This species has been in the aquarium trade since the early 1970s but its precise origin was a mystery until 2003. It first appeared in Ukraine, the common name 'Odessa' being derived from the port city of that name, and when it arrived in western Europe was widely considered a hybrid of similar-looking congeners such as P. conchonius, P. ticto and P. cumingii. It was also hypothesised as a subspecies of P. ticto or P. conchonius, and some suggested the fish to be artificially dyed.

This species is confused with P. ticto in much of the available literature and is sometimes listed as a synonym of it. Although some populations of the two species possess a similar colour pattern (there are reports of a P. ticto variant from the south of West Bengal state in India with a red, black-flecked dorsal-fin, for example) they do not occur in the same waters in nature and can be distinguished by examining the lateral line. This is complete in...

This species is traded on a fairly regular basis and is similar in appearance to some congeners, most notably S. bella, S. mahnerti, S. multifasciata, S. poculi, S. reticulata, S. longa, S. conirostris and S. udomritthiruji. This assemblage has been referred to as the Schistura multifasciata 'group', and members share a...

This species is also referred to as 'Asian knifefish' or 'ghost knifefish' in the aquarium trade in the aquarium trade but arguably has no place in the ornamental hobby given its adult size and specialised requirements. It is sometimes confused with the African species Xenomystus nigri but is easily told apart by its larger adult size and presence (vs. absence) of a dorsal fin.

This species is diagnosed by the following combination of characters: body moderate sized; head squarish; no proboscis or transverse groove on snout; mental disc length 96.9% its own width; pre...

Members of this assemblage can be told apart from other congeners by possession of 44–46 vertebrae, an adipose-fin with a relatively short base (< 20 % SL), a colour pattern comprising either distinct black spots arranged in vertical columns or irregular black vertical lines running along the flanks, and normally a reddish or orangish caudal-fin in life.
