概述
中华金沙鳅（Jinshaia sinensis）来自金沙江流域，是需要真正流水环境的爬鳅。它常见于坡度较大的溪流，饲养时重点是持续高溶氧、清洁水质和成熟岩石表面，不能仅靠外形将它当作普通底层伴鱼。
分布与栖息地
已知仅在中国长江水系的金沙江流域。栖息清澈、富氧的上游、急滩及小瀑流水段，底床有砂砾、岩石或基岩，附着生物丰富，水草只零星出现。
饲养环境
底面积至少参考 90 × 30 厘米。用砂砾和不同大小圆石模拟急流底部，可添沉木根枝，耐受的附生植物固定在硬景上。较强光照支持藻膜生长；强过滤配合造流、增氧，防止有机废物积累。稳定水质和生物膜都准备好后再放鱼。
食性与喂食
天然食物可能主要是底栖藻类及伴生微生物。可用优质干粮、富蔬菜和螺旋藻的凝胶食物补充，动物饵适量，蛋白过多可能带来问题。硅藻和软绿藻比硬黑毛藻适合，主缸不足时可另培长藻石轮换。瘦弱个体应先减少竞争、持续供食。
习性与混养
预计性情较温和，但仍有不确定性，伙伴首先要适应急流和高溶氧。六尾左右同养是参考近亲习性提出的建议，不能当作已经确认的野外群居规模；相似爬鳅之间可能有小争执。
雌雄区分
成熟雌鱼可能稍大、更丰满，仅可作为观察线索。
补充说明
较长且深叉的尾鳍可帮助与部分近似爬鳅区分。有关它游泳能力较强的说法仍带推测性，不宜据此取消贴附和休息表面。

Overview
Native to the Jinsha basin, Jinshaia sinensis requires a genuine running-water aquarium. High-gradient streams are characteristic, making oxygenation, cleanliness, and established rocky surfaces central rather than optional additions.
Distribution & habitat
Known records are confined to the Jinsha within the Yangtze system. Clear oxygen-rich headwaters, riffles, and cascades have gravel, stones, or bedrock with rich biofilm and only occasional aquatic plants.
Aquarium setup
Use at least a 90 by 30 cm footprint arranged as a rocky stream bed. Wood and attached hardy plants can be added. Strong lighting supports surface growth, while effective filtration, circulation, and aeration prevent stagnant, waste-laden conditions. Introduce fish only after both biological stability and biofilm are established.
Diet & feeding
Algae and associated organisms are the likely main natural foods. Suitable prepared foods and vegetable-rich gels can supplement grazing, with animal prey kept moderate. Diatoms and soft green algae are preferable to tough brush algae. Rotate cultured rocks if food surfaces are depleted, and protect weakened fish from competition.
Behaviour & compatibility
Peaceful behavior is expected but not firmly established. Match companions to the demanding water conditions. A group of about six is recommended by comparison with relatives, rather than based on confirmed wild group sizes, and similar loaches may squabble.
Sexual dimorphism
Mature females may be somewhat larger and fuller-bodied, offering only a tentative visual clue.
Notes
The relatively long, deeply forked tail helps distinguish it from some lookalikes. Claims of stronger swimming ability remain qualified and do not justify removing clinging and resting surfaces.
