概述
台湾间吸鳅（Hemimyzon formosanus）是台湾特有的急流鱼，在岛内同属成员中分布较广。它需要成熟岩石表面作为觅食场所，不能只凭外形像“清洁鱼”就投入新开的水族箱。
分布与栖息地
主要在中央山脉西坡河流较丰富，北部少数水系也有记录。生活于浅、急、富氧的上游和小支流，石块、砂砾和大卵石间有急滩及水潭，清澈水体和光照支持丰富附着生物。
饲养环境
底面积至少参考 120 × 30 厘米。砂砾底铺多种大小圆石，强过滤配合气石或造流，每小时循环可参考水体的 10–15 倍。较强照明培养藻膜，避免新沉木大量染水，耐受附生植物和外露海绵可增加食物表面。只入成熟稳定的缸，定期部分换水并保留多数附着物，盖严防攀爬。
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，红虫等动物饵适量，避免高蛋白过量。硅藻和软绿藻较适合，主缸供应不足时可另培长藻石轮换。瘦弱新鱼应先减少竞争并持续供食。
习性与混养
大体温和，但对同种略有领域意识，同时又需要同伴，建议至少四尾。其他鱼应能适应流水和高溶氧，相似爬鳅之间可能发生小争执。
雌雄区分
成年雌鱼可能较大、更丰满，这来自近亲的比较，不能作为已经确认的单一分性标准。
补充说明
腹鳍不像许多近似吸鳅那样形成完整吸盘，尾鳍略凹至浅叉。外形接近不代表生活习性或繁殖记录可以互相套用。

Overview
A Taiwanese endemic, Hemimyzon formosanus is relatively widespread among the island’s members of its genus. Established grazing surfaces are essential; its appearance as a clinging cleaner should not encourage introduction into a newly assembled aquarium.
Distribution & habitat
It is most abundant in rivers draining the western Central Mountain Range, with records from a few northern drainages. Shallow fast headwaters and tributaries contain mixed rocky beds, riffles, and pools. Clear oxygenated water and light maintain abundant surface growth.
Aquarium setup
Allow at least a 120 by 30 cm footprint, with varied smooth rocks over sand or gravel. Filtration and aeration should support the suggested turnover of 10–15 tank volumes per hour. Light encourages biofilm; avoid excessive staining from fresh wood. Hardy plants and exposed sponge surfaces add feeding area. Use mature stable water, make regular partial changes, and secure the lid against climbing escapes.
Diet & feeding
Its likely natural diet centers on algae and associated microorganisms. Supplement established grazing with suitable dry foods and vegetable-rich gels, using animal prey moderately rather than a high-protein regime. Diatoms and soft green growth are preferable to tough algae. Rotate cultured rocks if necessary, and give weakened arrivals uncontested food.
Behaviour & compatibility
Generally peaceful but somewhat territorial toward its own kind, it still benefits from companions. A minimum group of four is recommended. Choose fishes suited to current and oxygenation, allowing for minor disputes among similar loaches.
Sexual dimorphism
Adults that are larger and fuller-bodied may be females, but this comparison with relatives is not an established standalone sexing method.
Notes
The pelvic fins do not form the complete disc seen in many lookalikes, and the tail is notched to slightly forked. Similar appearance does not justify transferring another species’ breeding observations to this one.
