概述
Lepidocephalichthys zeppelini 是成年体长仅约 2.6 cm 的小鳅，雄鱼胸鳍上独特的双层板状结构，是识别的重要特征。体型虽小，仍需细砂、遮蔽与同种伙伴。
分布与栖息地
分布于泰国、越南的湄公河中下游水系，以及泰国中部湄南河流域。模式地位于泰国乌汶府 Mun 河支流区域。
模式地不少成鱼来自干燥农地中残留的季节性水洼；同时调查的小溪、沼泽和淹水稻田中，仅在一条砂底溪流发现一尾幼鱼。这种记录说明它并非只生活在常年流动的溪水中，却不表示饲养时应复制缺氧或干涸条件。
饲养环境
底面积至少约 45 × 30 cm，铺柔软细砂，供鱼埋入身体。粗砾可能造成紧张、擦伤和取食受阻。岩石与沉木先放稳，再铺砂，形成阴影和躲藏处。
使用较暗照明及少量落叶，保持温和水流与适当供氧。幼小个体容易钻进过滤设备，进水口需加防护，缸盖也应盖严。
食性与喂食
可能通过筛取底质捕食昆虫幼虫和小型甲壳动物。缸内可尝试小颗粒沉底干粮，并规律提供适口的水蚤、丰年虾或红虫等活饵、冻饵。食物大小要适合它很小的口部。
习性与混养
建议至少四条同种相伴。同属鱼通常温和，但可能吃卵或仔鱼。混养以环境要求相近、安静的小型上层鱼为宜；其他鳅类须避开强领域性或好斗种，以免小鱼被挤占空间和食物。
雌雄区分
雄鱼较小，胸鳍和腹鳍相对较大。成熟雄鱼第七、八胸鳍条形成两层突起：上方较大的圆角矩形板带约 25 个细锯齿，下方另有较小圆形板。雌鱼体侧多斑点，雄鱼常呈较窄深色侧线。
补充说明
深叉尾鳍上的暗色网纹、短触须及极小成体有助于辨认。种名来自 Led Zeppelin 乐队：命名者认为雄鱼胸鳍的双层结构让人联想到双颈吉他。搬运时仍应留意鳅科鱼类的眼下棘挂网风险。

Overview
Adult Lepidocephalichthys zeppelini reach only about 2.6 cm. The unusual double plate on mature male pectoral fins is a key identification feature. Despite its size, this loach needs proper sand, shelter, and company.
Distribution & habitat
Records cover the middle and lower Mekong in Thailand and Vietnam and the Chao Phraya basin in central Thailand. The type locality lies in the Mun drainage near Ubon Ratchathani.
Many adults were collected from temporary pools left in otherwise dry farmland. Surveys also included streams, marshes, and flooded rice fields, but yielded just one juvenile from a sandy stream. Permanent flowing channels therefore do not describe the entire habitat; seasonal drying and oxygen depletion are not conditions to reproduce in an aquarium.
Aquarium setup
Use at least about 45 × 30 cm of floor space with soft fine sand for burial. Coarse gravel can cause stress, abrasions, and difficulty feeding. Secure stones and wood before adding sand, creating shaded hiding places.
Subdued lighting and a modest layer of leaves suit the display. Maintain gentle circulation with adequate oxygenation. Protect filter intakes against tiny fish and keep the aquarium covered.
Diet & feeding
It probably extracts insect larvae and small crustaceans by sifting substrate. Try fine sinking dry food together with regular small live or frozen Daphnia, brine shrimp, or bloodworms. Particle size matters for such a small mouth.
Behaviour & compatibility
Keep at least four conspecifics. The genus is generally peaceful, although eggs or fry may be eaten. Choose calm small upper-water companions with matching environmental needs. Avoid aggressive or strongly territorial loaches that could displace these tiny fish or dominate food.
Sexual dimorphism
Males remain smaller and develop proportionately larger pectoral and pelvic fins. The seventh and eighth pectoral rays form a large rounded rectangular upper flange with about 25 fine serrations and a smaller rounded lower flange. Females tend to have flank spots, whereas males commonly show a narrow dark lateral stripe.
Notes
A forked tail with dark reticulation, short barbels, and very small adult size assist recognition. The name honors Led Zeppelin: the paired male structures reminded the authors of a double-neck guitar. Take care with the movable eye spines when netting.
