概述
杰氏兔鮡（Hara jerdoni）体型很小、性情温和，平时活动不多，却不能因此忽略水质与夜间进食。它喜欢柔软底床和充足藏身处，适合小型温和鱼的环境，不宜与活跃底栖鱼抢食。
分布与栖息地
来自印度和孟加拉国，生活在缓流溪流和小河，偏爱的地点有柔软底床，天然水体溶氧较高。
饲养环境
可从 30 × 20 × 20 厘米的小缸考虑，但水量少时要格外仔细维持稳定，不能把最低尺寸理解为容易管理。铺柔软细砂，多做躲藏处，搭配沉木和干燥落叶。保持水体清洁、偏凉并且溶氧充足。
食性与喂食
接受多种小颗粒食物，包括干颗粒，但应主要使用红虫、水蚤等活饵和冷冻饵。它严格在夜间进食，熄灯后再投喂，确认食物确实到达它活动的地方，避免被伙伴先抢光。
习性与混养
可与温和小鱼一起养，也适合与亚洲溪流小型鱼搭配。避开活跃的底栖鱼，它很容易在取食上处于劣势。同种相处没有明显问题，且更喜欢有同伴的群体。
雌雄区分
怀卵雌鱼可能显得更宽，但不是已经确认可靠的辨别方法。
繁殖
曾有人工繁殖，报道中卵似乎产在产卵拖把里。这个有限记录不能提供完整孵化和仔鱼饲养方法，卵的具体放置方式也应保留不确定性。
补充说明
较长的胸鳍硬棘是辨认特点之一。它及部分近亲从上方看轮廓和花纹像飞蛾，因此有相应俗名，但这种共同称呼不能代替物种识别。

Overview
Tiny and peaceful, Hara jerdoni is relatively inactive but still needs careful water-quality and feeding management. Soft substrate and numerous retreats suit it well. Active bottom-dwelling competitors are inappropriate, even if they otherwise appear harmless.
Distribution & habitat
It occurs in India and Bangladesh in slow streams and small rivers. Preferred sites have soft substrates and well-oxygenated water.
Aquarium setup
Dimensions of 30 by 20 by 20 cm are suggested as a starting point, but small volumes require especially careful control. Provide soft sand, numerous refuges, wood, and dried leaves. Keep the water clean, relatively cool, and well oxygenated.
Diet & feeding
Small pellets may be accepted, but live and frozen foods such as bloodworms and daphnia should form the main offerings. Feed after lights go out: this strictly nocturnal feeder otherwise risks missing its share, especially among competitors.
Behaviour & compatibility
It can share an aquarium with peaceful small fish, including suitable Asian stream species. Avoid active bottom feeders, which readily outcompete it. Conspecific company is well tolerated and a group is preferred.
Sexual dimorphism
Egg-filled females may appear broader, though reliable sex differences remain uncertain.
Breeding
Captive breeding has occurred, with eggs reportedly placed in spawning mops. The account does not establish a complete incubation or fry-rearing method, and the exact deposition behavior remains uncertain.
Notes
Elongated pectoral spines help distinguish it. The moth-like outline and pattern seen from above explain a shared common name with relatives, but that label does not identify the species by itself.
