概述
条纹准舌唇鱼（Lobocheilos rhabdoura）身体较修长、口较宽，吻部突起明显。它是强壮的附着生物刮食鱼，食物附近可能主动追逐其他鱼，需要宽敞流水环境。
分布与栖息地
见于湄公河、越南同奈河、泰国昭披耶河与湄功河，并延伸至泰国半岛和马来半岛北部小河系。常在石底、中等至较快流水中生活，也参与湄公河大规模季节迁移。
饲养环境
以石砾、圆石、沙和沉木建立溪流布局，附生水草固定于硬景即可。重点保持清洁、高溶氧及强效循环，可争取每小时循环超过缸水量 10 倍；光照能帮助硬表面形成生物膜。
食性与喂食
天然刮食附着生物与底栖藻等，石面可能留有进食刮痕。喂食需兼顾动物和植物成分，用红虫、丰年虾、碎虾肉等搭配植物含量较高的下沉饲料，不能只靠吃藻。
习性与混养
进食时会追赶进入附近的鱼，宜配活跃温和的伙伴，避免慢游和长鳍种。同种也会争执，特别是空间不足时；群养更接近野外松散聚集方式，但前提是足够大的缸。
雌雄区分
成年雌鱼体形更厚，雄鱼头部及吻部追星更发达。
繁殖
自然繁殖伴随季节性上溯，从湄公河下游、洞里萨迁往老挝境内中游地区，尚缺缸内繁殖记录。
补充说明
与舌唇鱼（Lobocheilos melanotaenia）相比，本种体高较低、口宽接近头宽，吻部突起较大，几项特征应一起比对。

Overview
The comparatively shallow body and broad mouth of Lobocheilos rhabdoura suit its distinctive appearance among related grazers. Feeding competition can involve active chasing, so the aquarium must provide substantial space as well as riverine conditions.
Distribution & habitat
Native records extend through the Mekong region and south into northern Peninsular Malaysia. Rocky streams and rivers of various sizes are used, and the species forms part of major seasonal migration assemblages.
Aquarium setup
Use a rocky stream setting with both browsing surfaces and open routes. Maintain clean highly oxygenated water and substantial circulation. Brightly lit hardscape supports biofilm, while robust attached plants can add cover.
Diet & feeding
Offer mixed animal and plant foods to complement natural surface grazing. Sinking preparations rich in vegetable ingredients can be alternated with small live or frozen invertebrates. Aquarium algae alone is insufficient.
Behaviour & compatibility
Choose agile peaceful companions able to avoid feeding-related pursuit. Slow or long-finned fishes are poor candidates. A social group is desirable, but inadequate space increases conspecific conflict rather than solving it.
Sexual dimorphism
Adult females are fuller, whereas males show more extensive tubercles on the head and snout.
Breeding
Wild reproduction involves seasonal migration toward the middle Mekong in Laos. A captive breeding procedure has not been demonstrated.
Notes
Separation from Lobocheilos melanotaenia uses the shallower profile, wider mouth and larger snout tubercles together.
