概述
印度低线鱲（Barilius shacra）在观赏鱼贸易中并不常见，体侧通常有约 12 条竖纹，背鳍上部带黑色横带。它善于快速游动、抢食积极，适合专门安排的流水大缸。
分布与栖息地
分布于尼泊尔及印度北部喜马拉雅山麓的恒河、布拉马普特拉河水系，也见于孟加拉国恒河下游。栖息在含氧充足、坡度中等至较大的河流和支流，水流中等至较快，底部多砾石、大石及裸露基岩。
饲养环境
布置时先留下开阔泳道，再加沙砾、圆石与少量沉木。可用过滤、造流及气石维持适度水流和高溶氧。必须等缸内生物过滤成熟后再放鱼，每周换水约 30%～50%，避免有机污染积累，并装严密缸盖防跳。耐受的附生水草可固定在石木上。
食性与喂食
天然食物以水面昆虫为主，也可能摄食小鱼和底栖小动物。人工饲养可用优质干粮搭配红虫、丰年虾及碎蚯蚓；果蝇、小蟋蟀应先喂养再投给鱼。
习性与混养
宜至少 5 条一起饲养，同种群体有明确等级。只养少数几条，弱鱼可能持续挨追；单养也可能转而攻击外形相近的鱼。体型相近、健壮的流水鱼更适合作伴，胆小慢游鱼与很小的鱼都应避开。
雌雄区分
怀卵雌鱼可能比雄鱼厚实，但这一外观差异尚未确认，不宜作为可靠鉴别方法。

Overview
An occasional export rather than a familiar aquarium staple, Barilius shacra usually shows about twelve flank bars and a dark band across the upper dorsal fin. Its vigorous swimming and feeding call for a spacious river aquarium with carefully matched companions.
Distribution & habitat
The species occurs in Himalayan foothill drainages of the Ganges and Brahmaputra, extending from Nepal and northern India to the lower Ganges in Bangladesh. It uses well-aerated river channels over gravel, cobbles, boulders and bedrock rather than sheltered stagnant habitat.
Aquarium setup
Keep an extensive clear swimming lane between rockwork and branches. Sand and mixed gravel suit the stream layout, with tough attached plants optional. A mature filter, adequate circulation and generous aeration are important; regular weekly changes of roughly 30–50% help prevent waste buildup. Fit a lid securely because powerful jumps are a real risk.
Diet & feeding
Surface insects provide its principal natural food. Other small animals, including fishes, may also be taken. Use varied live and frozen invertebrates alongside quality prepared food, and feed any terrestrial feeder insects well before offering them.
Behaviour & compatibility
A group of five or more allows social interactions to spread through a hierarchy. With only two or three, a subordinate fish may receive continual attention. Select sturdy tankmates able to cope with its speed and appetite; timid fish may miss meals, and much smaller ones may become prey.
Sexual dimorphism
Females carrying eggs are expected to look fuller, but a dependable external sexing method has not been confirmed.
