概述
Schistura aurantiaca 以体侧三至九道橙色竖带为主要辨识特征，前部身体和颈背大多呈均一褐色。它来自林荫溪流浅滩，养护重点是高溶氧、清洁水质和石木形成的遮蔽。
分布与栖息地
目前只记录于泰国西部北碧府，模式地点位于桂诺河支流卡延河，属美功河流域。栖地为林冠遮阴、清澈且富氧的源头溪流与小支流，砂砾、石块和大石混合，岸生植物发达，沉水植物不明显。
采集点的宽度、流量和水位随季节变化，说明野外条件并非全年固定。
饲养环境
可用大小不等的石块、砂、细砾及水磨大石模拟河道，沉木枝条形成缝隙、阴影并打断视线。强健附生植物能固定在石木上，不必强求一般水草茂盛。
不用制造极端急流，但要有较高溶氧及一定流动，过滤、造流或气石可按需要组合。对有机污染累积不耐受，每周约三至五成换水应规律执行。
食性与喂食
同属鱼总体杂食而偏向微小动物，植物与碎屑通常只占较少部分。可参考这种背景搭配适口干粮和每日小型活饵、冷冻饵；这并不等于本种天然食谱已经单独测定。
雌雄区分
描述中未发现明显的外观性别差异。
繁殖
人工繁殖尚无报告。
补充说明
第一道橙带在头后，第二道位于背鳍前缘附近。它可能与相似条纹鳅混批出口，商品标签未必能反映准确身份。

Overview
Orange flank bars distinguish Schistura aurantiaca, with much of the nape and front body remaining uniformly brown. Originating in shaded stream riffles, it needs clean oxygen-rich water and shelter among rocks and wood.
Distribution & habitat
Known records are confined to Kanchanaburi in western Thailand. The type site lies in the Khayeng, part of the Kwai Noi–Mae Khlong system. Forest shade covers clear, well-oxygenated headwater streams with sand, gravel, rocks, and boulders. Bankside growth is developed, while submerged plants are scarce.
Seasonal changes in width, flow, and depth show that natural conditions are not constant throughout the year.
Aquarium setup
Build a stream layout from mixed stones, sand, fine gravel, and worn boulders. Branches create crevices, shade, and interrupted sight lines. Tough attached plants can be used without expecting delicate vegetation to flourish.
Extreme current is unnecessary, but maintain high oxygen and some movement through filtration, pumps, or aeration. Routine weekly changes of roughly 30–50% help prevent poorly tolerated organic waste accumulation.
Diet & feeding
The genus is generally described as omnivorous with a strong small-animal component and relatively little plant matter or detritus. This provides a basis for combining suitable dry foods with daily small live or frozen meals, without establishing a separately measured natural diet for this species.
Sexual dimorphism
No obvious external sexual differences were identified in the description.
Breeding
Captive reproduction is unreported.
Notes
The first orange bar lies just behind the head and the second near the dorsal origin. It may be exported alongside similarly marked loaches, so a sales label need not establish exact identity.
