概述
Laubuka fasciata 是印度喀拉拉邦特有的小型鲤科鱼，深色纵带从眼延伸到尾柄。它会群游，也很会跳，饲养不能因体形小而省略开阔游动空间与严密缸盖。
分布与栖息地
分布于印度西南部喀拉拉邦多个河流系统，包括佩里亚尔河、恰拉库迪河等。通常在河流、溪流中下游的浅水岸边活动，偏好水流较慢、底部为岩石和砾石的区域。
饲养环境
缸底至少约 120 × 30 cm。用大小不同的岩石、砾石、磨圆大石与沉木枝条布置流水环境，可将耐受环境的附生水草固定在布景上，同时保留游动区。
需要持续洁净的水，不能任由有机废物积累。缸盖应贴合严密，防跳是实际需求，而非可有可无的附件。
食性与喂食
自然在水面捕食陆生和水生无脊椎动物。缸内可吃粒径合适的干粮，同时定期补充活或冷冻水蚤、丰年虾、红虫等，保持食物变化。
习性与混养
不具明显攻击性，可与环境需求相符、性情合适的其他鱼混养，不能仅因对方属于某一大类就认定相容。
至少 8～10 条同养较合适，群体可减少紧张，也更容易表现自然游动。空间应按整个群体安排。
雌雄区分
成年雌鱼明显更高身，通常也略大于雄鱼。
补充说明
深色眼至尾柄纵带、下颌散布的小突起与较长腹鳍都是鉴别线索。旧记录中可能写作 Laubuca fasciata 或 Chela fasciata，查找时要核对名称对应，而不是把拼写差别当作新鱼种。

Overview
Laubuka fasciata is a small cyprinid endemic to Kerala, India, with a dark stripe linking the eye and tail base. It schools and jumps effectively. Small body size does not remove the need for swimming space or a tightly secured cover.
Distribution & habitat
It occurs in several Kerala river systems in southwestern India, including the Periyar and Chalakkudy. Typical sites lie along shallow, slow-moving margins of middle and lower river or stream reaches, over rock and gravel.
Aquarium setup
Provide a footprint of at least approximately 120 × 30 cm. Mixed rocks, gravel, rounded boulders, and branches can create a flowing-water setting. Hardy attached plants can be fixed to the structure without occupying the open swimming area.
Organic waste buildup is poorly tolerated, making consistently clean water essential. A closely fitted cover is a practical necessity for jump prevention.
Diet & feeding
It naturally takes terrestrial and aquatic invertebrates at the surface. Appropriately sized dry food is accepted in captivity, but regularly include live or frozen Daphnia, brine shrimp, and bloodworms for variety.
Behaviour & compatibility
It is nonaggressive and can share accommodation with suitable fishes that match its conditions and temperament. Membership of a broad fish group alone is not evidence of compatibility.
Maintain at least eight to ten together. A group reduces nervousness and encourages natural swimming, so plan the enclosure around the whole group rather than one small fish.
Sexual dimorphism
Mature females are distinctly deeper-bodied and generally a little larger than males.
Notes
The dark eye-to-tail stripe, scattered lower-jaw tubercles, and elongated pelvic fins aid recognition. Older records may use Laubuca fasciata or Chela fasciata. Check name relationships rather than treating a different spelling or genus as a separate species.
