概述
萨尔温南鳅（Schistura maepaiensis）是较少见的溪流鳅，体侧不规则横纹带细暗色边缘。稳定后会守护洞隙，丰富遮蔽、干净富氧的水以及合适的同伴，比单纯追求强水流更重要。
分布与栖息地
确认分布于泰国西北湄宏顺和达府的萨尔温江支流，缅甸同水系的分布仍属可能。模式产地原为中等至较快水流的浅溪，底部由石块与大石构成。历史上该地点曾因人为活动迅速退化，但这不等同于整个物种已从其他地点消失。
饲养环境
以砂、细砾和不同大小圆石模拟河床，沉木枝条提供多处阴影、洞隙与视线屏障。可在硬景观上种附生水草。鱼会选择特定藏身处并驱赶同种和近似外形的鱼，应提供分散的退避空间。
保持高溶氧和适度水流即可，不需让全缸处于激流。过滤应有效，规律每周部分换水，避免有机污染积累。
食性与喂食
同属鳅的食物以小型动物为主，兼有少量植物和有机碎屑。缸中可用适口干饲料，搭配每日小型活饵或冷冻饵料，如水蚤、丰年虾和红虫。随水漂过的饵料有时会引起快速截食。
习性与混养
慢游、长鳍鱼和特别温顺的底栖鱼不适合，外形相近的其他鳅也需谨慎。温和、在开阔水层活动且适应流水的鲤科鱼，以及相合的吸鳅，可作为选择方向。
它不属于紧密群居种，结构丰富的缸内可以群养，但争执仍会发生；小缸或裸露布置会使同种攻击加重。不能因相较部分同属攻击性较低，就忽视每条鱼的藏身位置。
雌雄区分
雄鱼眼下有瓣状结构，胸鳍明显较长，部分鳍条带细小结节。雌鱼可能更丰满，抱卵时更明显。
补充说明
体侧约十至十三道不规则横纹及其细暗边缘，是较实用的识别特征；尾鳍起点黑纹分成两个近斑点状部分。水族繁殖尚无记录。

Overview
Schistura maepaiensis is a little-known stream loach with irregular body bars edged in darker pigment. Established fish defend shelters. Clean, oxygen-rich water, numerous refuges, and compatible companions matter more than simply maximizing current.
Distribution & habitat
Confirmed records concern Salween tributaries in northwestern Thailand. Occurrence in Myanmar's part of the system remains possible. The type locality was a shallow rocky stream with moderate to swift flow. Historical degradation at that site does not establish disappearance from all other localities.
Aquarium setup
Combine sand, fine gravel, and smooth stones with branches that create shaded gaps and broken sightlines. Hardy attached plants are possible. Fish select shelters and defend them against conspecifics and similar-looking species, so distribute retreats throughout the aquarium.
Maintain high oxygen availability and suitable circulation without needing extreme torrent conditions. Effective filtration and regular weekly partial changes prevent organic pollution from accumulating.
Diet & feeding
The genus is described as consuming predominantly small animal prey with lesser plant material and detritus. Combine suitable dry foods with daily live or frozen offerings such as water fleas, brine shrimp, and bloodworms. Passing food may be intercepted with a quick upward movement.
Behaviour & compatibility
Avoid slow fishes, trailing fins, and very placid bottom dwellers. Similar-shaped loaches can also be problematic. Peaceful open-water cyprinids from flowing habitats and compatible hillstream loaches are more suitable options.
It is not tightly social, although a group can coexist in a complex setup. Disputes remain possible and become more serious in cramped or sparsely furnished aquariums. Its comparatively moderate aggression does not remove the need for separate shelters.
Sexual dimorphism
Males have a suborbital flap and longer pectoral fins, with small tubercles on some rays. Females may be fuller-bodied, especially when carrying eggs.
Notes
Roughly ten to thirteen irregular, dark-edged bars and a tail-base marking divided into two spots help identification. Aquarium breeding is unrecorded.
