概述
深线平鳍鳅（Homaloptera bilineata）背前方两条深色线在背鳍处汇合，不形成许多近亲常见的鞍斑，是较实用的辨认线索。它来自清澈急流，适合成群在成熟岩石表面活动。
分布与栖息地
记录包括缅甸锡当河和萨尔温江水系、泰国西北部及西部湄功河支流；尼泊尔的记录存疑。常在清澈富氧的浅急流和上游浅滩活动，石砾或基岩覆有生物膜，河岸植被较发达。
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。强过滤和增氧造流维持清洁富氧水体，每小时循环可参考水体的 10–15 倍。根枝、沉木及耐受附生植物可提供休息面。只入成熟稳定的缸，规律部分换水但保留多数附着物，盖严以防攀玻璃逃出。
食性与喂食
可参考同属刮食生物膜和小型无脊椎动物的方式，保留长有附着物的石面。部分下沉干粮可能接受，但定期水蚤、丰年虾、红虫等活冷冻饵仍很重要。明显瘦弱的个体先降低食物竞争，持续提供容易吃到的合适饵料。
习性与混养
并不好斗，伙伴主要受流水和溶氧要求限制，相似爬鳅间可能轻微争执。建议六尾以上同养，数量少时较退缩；群体有时会靠近彼此、一起迎着水流排列。
雌雄区分
成熟雌鱼通常稍大、更丰满。
补充说明
从吻部向后的双条纹比笼统的“蜥蜴鳅”商品名更有辨认价值。体表鳞片有棱脊，不能把扁平腹部误解为全身无鳞。

Overview
Two dark stripes converging near the dorsal fin distinguish Homaloptera bilineata from relatives with saddle-shaped markings. It is a current-loving loach best observed in a group over established rocky surfaces.
Distribution & habitat
Records span the Sittaung and Salween systems of Myanmar and parts of northwestern and western Thailand, including Mae Klong tributaries. Nepalese records are questionable. Clear oxygenated riffles and runs have rocky substrates with biofilm and well-developed bankside vegetation.
Aquarium setup
Use at least a 120 by 30 cm footprint with varied rounded rocks over sand or gravel. Effective filtration, oxygenation, and circulation should support the suggested turnover of 10–15 tank volumes per hour. Wood and hardy attached plants add resting surfaces. Maintain a mature stable system, retain biofilm during partial water changes and cleaning, and close the aquarium securely.
Diet & feeding
Genus-level feeding accounts describe biofilm and small invertebrate grazing. Keep mature surfaces available and offer regular live or frozen prey. Some sinking dry foods may be accepted, but should not be the sole assumption. Thin fish need accessible meals without competition while recovering.
Behaviour & compatibility
It is not aggressive, although related loaches may have minor disputes. Suitable companions must share its water requirements. Groups of six or more are recommended; smaller numbers are less confident. Individuals may arrange themselves close together facing into the current.
Sexual dimorphism
Mature females are usually somewhat larger and fuller-bodied.
Notes
The paired dark dorsal lines are more useful than a generic lizard-loach label. Keeled scales are present, so the flattened underside should not be mistaken for whole-body scalelessness.
