概述
李氏平鳍鳅（Pseudohomaloptera leonardi）来自马来半岛，是较隐蔽的流水爬鳅。扁平身体和展开的偶鳍使它能紧贴硬物，在石面爬行或短距离跳移，适合有丰富休息面、充足溶氧和同伴的成熟缸。
分布与栖息地
模式地点在马来西亚彭亨瓜拉大汉，分布向北延至泰国素叻他尼的塔比河水系；泰国其他河系和柬埔寨、尤其湄公河的记录仍需确认。成鱼常在清澈急流的浅石滩，幼鱼更多利用缓流砾底及淹没树根，岸边植被通常发达。
饲养环境
底面积可参考 80 × 30 厘米。砂砾底铺大小圆石，配沉木根枝和耐受附生植物。强过滤按需增加造流、气石，每小时循环可参考水体的 10–15 倍。只入生物系统成熟、水质稳定的缸，定期部分换水但保留附着生物。它能攀玻璃，缸盖必须贴合。
食性与喂食
可借鉴相关平鳍鳅刮食生物膜及小型无脊椎动物的方式，保持成熟石面并定期投喂水蚤、丰年虾、红虫等活冷冻饵。部分下沉干粮可能接受。消瘦个体需先避开竞争，保证连续获得适口食物。
习性与混养
并不好斗，但天性隐蔽，伙伴须适应同样水流、溶氧与水质。相似爬鳅可能发生轻微争执。四尾以上同养是参考相关平鳍鳅习性提出的建议，不宜仅养一尾并期待它充分展现活动。
雌雄区分
成熟雌鱼通常稍大，体形也更丰满。
补充说明
与其他外形相似的平鳍鳅容易混淆，仅靠“蜥蜴鳅”等商品名不够；胸鳍鳍条组合是区分近似种的重要特征，需要结合清楚的形态观察。

Overview
A retiring loach from the Malay Peninsula, Pseudohomaloptera leonardi clings to hard surfaces with its flattened body and spread paired fins. It often moves in short crawling or hopping steps, making abundant resting surfaces and stable oxygen-rich water central to aquarium care.
Distribution & habitat
The type locality is Kuala Tahan in Pahang. The accepted range extends through Peninsular Malaysia to the Tapi basin of southern Thailand; records farther afield, including the Mekong, remain unconfirmed. Adults favor shallow rocky riffles, while juveniles more often use slower gravel stretches with submerged roots.
Aquarium setup
Provide a suggested footprint of at least 80 by 30 cm with rounded rocks, sand or gravel, wood, and hardy attached plants. Filtration with additional circulation or aeration should support the suggested turnover of 10–15 tank volumes per hour. Use mature stable conditions, retain biofilm during partial water changes, and fit the cover securely against climbing.
Diet & feeding
Related-loach feeding guidance combines established biofilm with small invertebrates. Offer regular live or frozen prey and retain grazing surfaces; some sinking prepared foods may also be accepted. Thin individuals need food that is easy to reach without competition while recovering.
Behaviour & compatibility
It is not aggressive but is naturally reclusive. Choose companions for matching environmental needs, and watch for minor disputes with similar loaches. Keeping four or more follows guidance based on related loaches and offers more opportunity for natural activity than an isolated individual.
Sexual dimorphism
Mature females are usually somewhat larger and fuller-bodied.
Notes
Several similar loaches have been confused in trade. Pectoral-ray structure helps distinguish them, so a general lizard-loach label is insufficient for reliable identification.
