概述
湄公南鳅（Schistura kengtungensis）来自湄公河中游的浅溪流，体侧多为较宽暗纹。缸内行为经验有限，不能只凭小体型就认为适合普通社区缸，尤其应避开行动慢或鳍很长的同伴。
分布与栖息地
分布于泰国北部及东北部、缅甸、中国云南西双版纳和老挝的湄公河中游水系，老挝记录包括南本、南塔等支流。中国个体与泰国、缅甸个体在形态上有一些差异，来源应分别保留。
栖息于浅而窄的支溪，底部为砂砾或石块。泰国北部一处地点为急流跌水的山溪，宽度有限，石块和巨石构成复杂底部。
饲养环境
可采用流水溪流布局，混合砂、细砾和不同大小圆石，沉木枝条提供洞隙、阴影和视线屏障。耐受的水榕、铁皇冠等可附在景物上。
无需追求激流冲击，但应保持充足溶氧和一定水流。规律每周部分换水，避免有机污染积累，并保持过滤有效。
食性与喂食
同属鳅的食物通常以小昆虫、蠕虫、甲壳动物等为主，兼有较少植物及碎屑。缸内可尝试适口干饲料，但需搭配每日小型活饵或冷冻饵料，例如水蚤、丰年虾和红虫，不能仅依赖干粮。
习性与混养
实际水族行为尚不清楚。体形看起来较强健，宜避开慢游、长鳍或特别温顺的鱼；现有信息不足以给出无条件安全的混养组合。
雌雄区分
成熟雌鱼可能比雄鱼更厚实，这一判断仍属一般线索，不能当作确定的单项鉴别。
补充说明
体侧常有九至十三道与间隔等宽或更宽的暗纹，有时断裂或不够清晰。不同产地在吻形、腹鳍长度及尾基黑纹上有差异，暂不宜自行拆成新种。水族繁殖尚无记录。

Overview
Schistura kengtungensis is a broadly barred loach from shallow tributaries of the middle Mekong system. Captive behavior is poorly known. Small size alone is not a reason to place it with slow or long-finned community fishes.
Distribution & habitat
Its range includes northern and northeastern Thailand, Myanmar, Xishuangbanna in Yunnan, and several Lao tributaries of the middle Mekong. Chinese specimens differ morphologically from fish examined in Thailand and Myanmar, so locality information is worth retaining.
It uses shallow, narrow stream branches over gravel and stones. One northern Thai locality was a fast mountain stream with cascades and a rocky, boulder-filled bed.
Aquarium setup
A flowing-stream layout can combine sand, fine gravel, varied smooth stones, and wood. Create shaded gaps and interrupted sightlines. Hardy attached plants are suitable options.
High oxygen availability and some circulation matter more than reproducing violent torrents. Maintain effective filtration and regular weekly partial changes because organic pollution is poorly tolerated.
Diet & feeding
Related loaches are described as taking mainly small animal prey with lesser plant material and detritus. In captivity, suitable dry foods can be combined with daily small live or frozen offerings such as water fleas, brine shrimp, and bloodworms. Dry products alone are not recommended.
Behaviour & compatibility
Aquarium behavior remains unknown. It appears robust, making slow-moving, long-finned, or exceptionally placid companions inadvisable. Available information does not establish a universally safe community combination.
Sexual dimorphism
Mature females may have a deeper body than males. This remains a tentative clue rather than a confirmed single diagnostic.
Notes
Nine to thirteen dark bars are commonly as wide as, or wider than, the pale intervals, though bars can be incomplete or poorly contrasted. Regional differences in snout shape, pelvic-fin reach, and tail-base markings do not by themselves justify naming separate species. Aquarium reproduction is unrecorded.
