概述
Danio dangila 体型较大、游动活跃，特别长的须和体侧环状花纹很醒目。它通常不会主动攻击异种，但迅速游动、抢食的方式会让胆小或迟缓的伙伴受压。
分布与栖息地
记录主要集中在尼泊尔，以及印度和孟加拉国的布拉马普特拉河流域，亦有不丹、缅甸记录。被描述为广布恒河水系，但不同地区种群的身份和分布边界仍需谨慎看待。栖息环境从山地溪流到有植物的缓流水域、沼泽都有，并非只住急流。
饲养环境
提供充足长距离游动空间，可用砂砾、圆滑石块、沉木和耐附生植物布置。水必须清洁且溶氧充足，用可靠过滤维持水流，同时留出可避开直接冲流的位置。每周换掉约三至五成水，避免有机物积累。
食性与喂食
野外可能以昆虫及幼虫为食，这一判断仍带推测性。水族箱中通常接受干饲料，定期搭配红虫、水蚤和丰年虾等小型活饵、冷冻饵。
习性与混养
以八至十尾或更多的群体饲养，让追逐和等级互动主要发生在同种之间。混养宜选择体型相近或稍大、同样健壮的鱼；温吞、胆小的种类容易被持续活动和猛烈进食干扰。
雌雄区分
雌鱼腹部较丰满；雌鱼臀鳍外缘偏白，雄鱼则偏红。
繁殖
繁殖方式为散卵、不护卵，但可靠的水族箱繁殖记录尚不能确认。有些曾被归给本种的繁殖经历实际涉及另一种鱼，不能直接当作本种已成功人工繁殖的依据。

Overview
Long barbels and ring-like flank markings distinguish Danio dangila, a relatively large and energetic danio. Its pace and feeding enthusiasm matter more to compatibility than overt aggression.
Distribution & habitat
Most documented localities lie in Nepal and the Brahmaputra system of India and Bangladesh, with records also from Bhutan and Myanmar. The often-stated broad Ganges range warrants caution because geographic forms may involve unresolved identification. Habitats include hill streams as well as sluggish, vegetated waters and swamps.
Aquarium setup
Provide a long swimming area among sand, gravel, rounded rocks, wood, and robust attached plants. Efficient filtration should maintain clean, well-oxygenated water with useful circulation and areas sheltered from direct flow. Weekly changes of around 30–50% help prevent organic waste buildup.
Diet & feeding
Insects and larvae are considered likely natural foods. Most aquarium specimens take dry diets, supplemented regularly with small live or frozen offerings such as Daphnia, Artemia, and bloodworms.
Behaviour & compatibility
A group of eight to ten or more helps direct hierarchy-related interactions within the shoal. Robust companions of similar or somewhat larger size are preferable. Shy, slow fish can struggle alongside such constant movement and vigorous feeding.
Sexual dimorphism
Females are fuller-bodied. The outer anal-fin margin is whitish in females and reddish in males.
Breeding
It is described as an egg-scatterer with no parental care, but confirmed aquarium breeding remains unclear. A formerly attributed captive spawning account concerns a different species, so it cannot establish successful reproduction of this fish in captivity.
