概述
韦氏平鳍鳅（Homalopteroides weberi）来自婆罗洲砂拉越，已知范围可能只限于该州。它和相似种曾有分类争议，照顾时应先确认身份，不能把其他“蜥蜴鳅”的经验不加区分地套用。
分布与栖息地
模式地点是马来西亚砂拉越的阿卡尔河。栖息清澈、富氧的急流和上游浅滩，底床由砂砾、石块或基岩组成，表面覆有附着生物，水草通常只有零星分布。
饲养环境
底面积至少参考 60 × 30 厘米。用砂砾和大小圆石构建底部，沉木根枝及耐受附生植物可提供停驻面。强过滤维持清洁，气石和造流按需补充，每小时循环可参考水体的 10–15 倍；生物系统成熟稳定后再放鱼。
食性与喂食
可按同属捕食小型无脊椎动物的方式，定期提供水蚤、丰年虾、红虫等活冷冻饵。部分下沉干粮可能接受，不能把可能吃干粮视为无需其他食物。明显瘦弱的个体先避开竞争，确保连续取得适口饵料。
习性与混养
不是好斗类型，伙伴须适应同样的水流和溶氧，近似爬鳅之间可能轻微争执。建议六尾以上同养，小群可能较不大胆。
雌雄区分
近亲成熟雌鱼通常稍大、更丰满，这只能作为本种的参考线索，尚不能视为确定的分性方法。
补充说明
尾鳍两道暗带、相对较长的胸鳍，以及可伸至肛门附近或后方的腹鳍可辅助辨认，需结合整体形态而非单一条纹。

Overview
Known from Sarawak, Homalopteroides weberi may be restricted to that part of Borneo. Its separation from a similar species has been debated, making careful identification preferable to treating all lizard loaches as interchangeable.
Distribution & habitat
The type locality is the Akar River in Sarawak. Clear oxygenated streams and headwaters provide riffles and runs over gravel, rock, or bedrock with biofilm. Aquatic plants are generally patchy.
Aquarium setup
Provide at least a 60 by 30 cm footprint with rounded rocks over sand or gravel. Wood, roots, and hardy attached plants supply resting surfaces. Filtration with supplemental circulation or aeration should support the suggested turnover of 10–15 tank volumes per hour. Stable, biologically mature water is required before introduction.
Diet & feeding
Genus-level advice describes small invertebrate prey. Offer regular live or frozen Daphnia, Artemia, bloodworms, and similar foods. Sinking dry foods may be accepted, but acceptance should not be assumed to replace the rest of the diet. Thin fish need easy access to food without competitors.
Behaviour & compatibility
It is not aggressive, although similar loaches may have minor disputes. Match companions to the environmental requirements. Six or more together are recommended because smaller groups may remain less confident.
Sexual dimorphism
The larger, fuller females seen in related species provide a possible comparison, not a confirmed sexing method for this fish.
Notes
Two dark tail bands, relatively long pectorals, and pelvic fins reaching toward or beyond the anus contribute to identification. Use the combination rather than one isolated marking.
