概述
裸腹平鳍鳅（Homalopterula gymnogaster）来自苏门答腊高地，既有急滩也有“安静水域”的记录。湖泊名称不一定代表鱼就生活在湖内，也可能来自出水河流；饲养时仍应重视清洁、高溶氧和稳定环境。
分布与栖息地
模式地点为印度尼西亚苏门答腊马宁焦湖，可能实际采自出水的安托坎河。其他记录从占碑向北延伸至北苏门答腊，包括高海拔火山口湖附近；具体来自静水湖盆还是出湖水道，尚不能一概确定。
饲养环境
底面积可参考 80 × 30 厘米。砂砾上铺大小圆石，配沉木根枝和耐受附生植物，形成多处休息面。强过滤按需加增氧和造流，每小时循环可参考水体的 10–15 倍。只入成熟稳定的缸，定期部分换水，同时保留大部分表面附着生物。
食性与喂食
同属刮食生物膜及小型甲壳类、昆虫幼虫等。可定期给水蚤、丰年虾和红虫等活冷冻饵，部分下沉干粮可能接受，同时保留有附着物的石面。瘦弱鱼先在竞争少的环境恢复，食物须持续且容易取得。
习性与混养
近亲经验提示它可能不强烈攻击其他鱼，但仍需观察实际表现。建议六尾以上，数量少时较退缩，群体有时会紧靠并共同迎流。伙伴要适应相近水质和溶氧，相似爬鳅之间可能小争执。
雌雄区分
成熟雌鱼可能稍大、更丰满，体形分性仍带不确定性。
补充说明
体形较圆柱状、口较宽、偶鳍较短，尾缘近截形或略凹。腹部局部无鳞与种名有关，不能据此认定全身无鳞。

Overview
A Sumatran highland loach, Homalopterula gymnogaster has records associated with both riffles and quiet water. Lake-locality names may refer to fish taken from outlets rather than the lakes themselves, so oxygenation and stable water remain central to care.
Distribution & habitat
The type locality is Lake Maninjau, possibly referring to its Antokan outlet. Other records extend northward from Jambi into North Sumatra and include high-elevation crater-lake localities. Whether particular specimens came from lake basins or flowing outlets remains unresolved.
Aquarium setup
An 80 by 30 cm footprint is the suggested reference. Sand or gravel, rounded rocks, wood, and hardy attached plants supply varied resting surfaces. Filtration and aeration should support the suggested turnover of 10–15 tank volumes per hour. Use mature stable water, make regular partial changes, and retain established surface growth.
Diet & feeding
Genus-level feeding accounts include biofilm and small invertebrates. Supply regular live or frozen prey and established grazing surfaces; some sinking dry foods may also be accepted. Weakened fish need readily available suitable food without competition while recovering.
Behaviour & compatibility
Experience with relatives suggests limited aggression, but that remains unconfirmed for this fish. Six or more are recommended to reduce shyness; groups may gather facing the flow. Assess companions for shared environmental needs and possible minor loach disputes.
Sexual dimorphism
Mature females are probably a little larger and fuller-bodied, so body shape remains a tentative clue.
Notes
A more cylindrical body, broad mouth, short paired fins, and a truncate or slightly notched tail help characterize it. Localized abdominal scalelessness does not imply a scaleless body.
