概述
Danio jaintianensis 是来自印度东北部丘陵的小型群游鱼，性情温和，但适合较凉的水体。它并不适合常年高温的普通热带混养缸，夏季维持适温和溶氧比复杂造景更关键。
分布与栖息地
已知范围限于印度梅加拉亚邦贾因蒂亚丘陵，属于布拉马普特拉河水系。该地区多雨、林地丘陵广布；本种可能主要住在流速较缓的小型山溪，底部有石砾，岸边及上方有较密植物遮蔽，具体栖地偏好仍带推测。
饲养环境
可用深色底砂密植，或以圆滑石砾、沉木和耐附生植物布置溪流环境。提供适度水流而不是无处躲避的强冲流，并盖严缝隙。按适合它的较凉温度管理，避免长期过热；温暖季节加强增氧，并随活动与摄食需要调整喂食。
食性与喂食
野外很可能捕食昆虫及幼虫。缸养通常接受多种食物，用合口干饲料配合水蚤、丰年虾、红虫等活饵或冷冻饵，有利于体色与状态。
习性与混养
更适合单种展示，或与同样耐较凉水温的小型温和鱼同养。八至十尾以上可减少惊慌，雄鱼在群体中也更容易展示体色。选择底层伙伴时同样先核对温度、体型和活动方式，不能只按“底层鱼”这一类别搭配。
雌雄区分
预计成熟雌鱼比雄鱼略大、腹部较圆，颜色也较淡；这些区别应结合成熟状态判断。
繁殖
尚无明确繁殖报告，散卵且不护卵只是参照同类作出的推测。若尝试，可借鉴同属流程：调理亲鱼，在成熟的独立缸中提供莫丝、拖把或隔卵网，选一两对状态好的成鱼，以小量较凉新水或晚间换水尝试诱产。
如有卵，应及时隔离成鱼，改用海绵过滤保护鱼苗。预备草履虫级微食物，之后再逐步使用丰年虾无节幼体或微虫；近亲的孵化时程不是本种已验证的数据。

Overview
The peaceful schooling Danio jaintianensis favors cooler conditions than many tropical community fishes. Its temperature needs deserve priority over elaborate decoration, particularly during warm weather.
Distribution & habitat
Records are restricted to the Jaintia Hills of Meghalaya, northeastern India, in the Brahmaputra system. This wet, wooded region contains many fast upland waters, but the species is thought to favor smaller, slower streams with gravel, rocks, and substantial bank or overhanging vegetation.
Aquarium setup
A dark, well-planted aquarium or a layout of smooth stones, gravel, wood, and attached plants is suitable. Use moderate circulation with sheltered areas and seal the cover carefully. Maintain its cooler recommended conditions and prevent prolonged overheating. Increase aeration during warmer periods and adjust feeding to activity and appetite.
Diet & feeding
Insects and larvae are considered likely natural foods. Most aquarium foods are accepted; combine suitable dry items with small live or frozen Daphnia, Artemia, and bloodworms for condition and color.
Behaviour & compatibility
A species display is a good choice, with other small fishes that appreciate cooler water as possible companions. Keep at least eight to ten so fish feel secure and males can display. Bottom-dwelling companions must also match its temperature and behavioral needs.
Sexual dimorphism
Mature females are expected to be slightly larger, rounder in the abdomen, and less colorful than males.
Breeding
Breeding has not been confirmed; an unguarded egg-scattering pattern is inferred from relatives. A trial could use conditioned pairs in an established separate tank with moss, mops, or egg-protecting mesh. Small additions of cooler water or an evening water change may help.
If eggs are obtained, separate the adults and protect young with sponge filtration. Prepare infusoria-sized food before progressing to Artemia nauplii or microworms. Incubation schedules from relatives remain unverified for this species.
