Identification
A dark blotch near the rear of the body and dark marks toward the tips of the forked tail are useful features. Adult males develop filament-like extensions from branched dorsal-fin rays. Similar barbs and older broad identifications require care when comparing records.
Size and Weight
The reported maximum total length is 18 cm, about 7.1 inches. A study of four southern Indian river sites recorded a maximum sample weight of 44.87 g, approximately 1.58 ounces. That measured weight describes the study sample, not a worldwide record or the mass of the longest reported fish.
Habitat and Natural Food
This barb occupies a broad range of waters in peninsular India, from streams to lowland rivers and wetlands. Documented food includes insects, other invertebrates and detritus. Its varied diet should not be reduced to an unverified claim about one best hook bait.
Breeding and Human Interest
Ornamental-fish research has documented induced breeding and early development in captivity. Those hatchery observations demonstrate a way to produce young fish; they do not establish the exact timing or success of spawning at every natural site.
The Fin Behind the Filament Name
The trailing rays are a male feature that develops with maturity. They complement the dark rear-body blotch and marked tail, giving a recognizable appearance beyond a generic silver barb.
