概述
Devario neilgherriensis 是观赏鱼贸易中极少见的山溪鱼。银色体侧带有宽而模糊的钢蓝色横带，上下各镶一条细黄色线，鳍偏黄并带细小黑点。
分布与栖息地
似乎局限于印度南部泰米尔纳德邦尼尔吉里山区的巴瓦尼河支流，包括派卡拉等溪流。栖地为清澈、含氧丰富的山溪及小河上游，部分地点海拔约 2000 m；沙砾与石块构成底部，岸边植被提供遮蔽，水量、流速和浑浊程度随季节变化。
饲养环境
可以溪流式环境作为尝试，用沙、细砾、圆滑河石和沉木布置，并加入耐养附生水草。可能不耐有机污染，建议维持洁净水体、良好溶氧与适度水流，每周换水约三成至一半。缸盖必须贴合，防止跳跃。
食性与喂食
野外很可能以昆虫和幼虫为主。人工环境可采用优质干粮搭配红虫、水蚤、丰年虾等小型活饵或冷冻饵，观察接受程度与体况。
习性与混养
推测并非攻击性强的鱼，但活跃游动和抢食可能压制慢游或胆小的伙伴。可优先考虑体型相近、健壮且需求一致的鱼，并维持八至十尾或更多的同种群体。基于近缘鱼经验，群体数量可能有助于分散等级冲突，仍需观察个体差异。
雌雄区分
成熟雌鱼一般可能略大、腹部更圆、体色较淡。

Overview
Devario neilgherriensis is a hill-stream fish almost unknown in the aquarium trade. Its described pattern combines silver flanks with a broad, indistinct blue band edged by narrow yellow lines; yellowish fins carry small dark specks.
Distribution & habitat
It appears confined to tributaries of the Bhavani system in the Nilgiri Hills of Tamil Nadu, southern India. Clear, oxygen-rich upland streams contain gravel, rocks and some marginal cover. Several sites lie near 2,000 m elevation, and seasonal changes strongly affect flow, volume and turbidity.
Aquarium setup
A river-style layout is a reasonable starting point, using sand, gravel, smooth stones and wood with hardy attached plants. Sensitivity to accumulating organic waste is considered likely. Maintain clean water, good oxygenation and moderate circulation, with weekly changes of around a third to half of the volume. A secure lid is needed to prevent jumping.
Diet & feeding
Insects and larvae are thought to be the principal natural prey. Offer quality prepared foods with regular small live or frozen items, checking acceptance and body condition.
Behaviour & compatibility
Serious aggression is not expected, but active swimming and feeding may intimidate slower or timid fishes. Robust companions of similar size and matching requirements are more promising. A group of eight to ten or more is suggested. Experience with relatives indicates that adequate numbers may distribute social tension, though individual responses still need observation.
Sexual dimorphism
Mature females are expected to be slightly larger, fuller-bellied and less intensely colored.
