概述
里氏平鳍鳅（Homalopterula ripleyi）来自苏门答腊北部小片山地水系。实际采集环境既有缓流石底林溪，也有铺满落叶的浅泉溪，不能只按“急流爬鳅”外形把所有空间布成裸石强流。
分布与栖息地
记录集中在多巴湖北侧至亚齐边界之间巴里桑山脉东坡河流。重新发现时，一处为清澈缓流的岩石、卵石及砾石小溪，另一处为竹林和灌丛遮阴、底部积厚落叶的泉水溪，水体都很浅。
饲养环境
底面积可参考 80 × 30 厘米。砂砾、大小圆石、根枝和耐受附生植物形成多种表面，避免整个底部都被强水流直冲。过滤和增氧保持清洁稳定，每小时循环可参考水体的 10–15 倍，按需要加造流或气石。成熟后再放鱼，规律部分换水但保留附着生物。
食性与喂食
可借鉴相关爬鳅刮食生物膜及小型无脊椎动物的喂养方式。定期喂水蚤、丰年虾、红虫等活冷冻饵，并保留石面附着物；部分下沉干粮可能接受。消瘦个体先避开竞争，保证持续获得适口食物。
习性与混养
近亲经验提示它可能不强烈攻击其他鱼，但本种混养表现仍需观察。建议六尾以上，同伴过少时较退缩；群体有时会靠近彼此、一起面向水流。伙伴宜能适应相近环境，并留意相似爬鳅间的小争执。
雌雄区分
成熟雌鱼可能稍大、更丰满，体形只能作初步线索。
补充说明
背部八至十块鞍斑不延伸到侧线，尾鳍后部有宽暗带，尾缘略斜且上叶稍长。腹面无鳞不等于整条鱼无鳞。

Overview
Known from a restricted northern Sumatran area, Homalopterula ripleyi has been collected in both slow rocky forest streams and shallow leaf-filled spring runs. Its loach-like form should not erase this habitat variety when planning an aquarium.
Distribution & habitat
Records are concentrated on the eastern Barisan slopes from north of Lake Toba toward Aceh. Rediscovery sites included a clear, slowly flowing rocky tributary and a shaded spring-fed stream with deep leaf deposits. Both were very small, shallow channels.
Aquarium setup
An 80 by 30 cm footprint is the suggested reference. Use varied rocks, sand or gravel, wood, and hardy plants while retaining sheltered patches. Filtration and aeration should support the suggested turnover of 10–15 tank volumes per hour without directing equal force everywhere. Introduce fish only to mature conditions and retain surface growth during regular maintenance.
Diet & feeding
Related-loach feeding guidance combines biofilm with small invertebrates. Provide regular live or frozen foods and established grazing surfaces, with sinking prepared food only if accepted. Weak, thin fish need easy access to suitable meals without competitors.
Behaviour & compatibility
Experience with relatives suggests limited aggression, but this is not confirmed for the species. Groups of at least six are recommended to reduce shyness, and fish may gather facing the flow. Companion choice still requires compatible conditions and observation of disputes.
Sexual dimorphism
Mature females may be larger and fuller-bodied, a tentative rather than definitive clue.
Notes
Eight to ten dorsal saddles stop above the lateral line. A broad dark rear tail band and obliquely truncate tail with a slightly longer upper lobe provide additional clues. Ventral scalelessness is not whole-body scalelessness.
