概述
Lepidocephalichthys sp. 'LE1' 是尚未确定种名的小型鳅类，英文贸易名为 Vietnamese Marbled Hog-faced Loach。饲养重点是细软砂底、同种伙伴和安静环境，不能凭商品名将它认定为已描述的近似种。
分布与栖息地
现有分布信息指向越南，具体采集地可能在中部岘港区域，但尚未确认。实际生境也未确定；同属鱼常见于浅缓溪段、沼泽、牛轭湖、回水与稻田，底部有软泥、沉积物、根枝或落叶，水深和水质可随季节变化。这些近亲经验仅供布置参考。
饲养环境
建议底面积至少约 45 × 30 cm，铺柔软细砂。鱼可能完全埋入其中，只露眼睛；粗砾会增加损伤和紧张，也可能妨碍觅食。沉木、平滑石块及根枝先放稳，再铺底砂，避免钻掘后坍塌。
用较暗灯光和少量落叶形成阴影，保留多个隐蔽位置。过滤以缓和水流配合适当供氧为宜，进水口要防小鱼钻入，缸盖也须严密。
食性与喂食
同属鱼通常筛取底质中的昆虫幼虫、小型甲壳动物等食物。缸内可投适口沉底干粮，并定期补充水蚤、丰年虾和红虫等小型活饵或冻饵。应观察藏在砂中的鱼是否能吃到足够食物。
习性与混养
建议至少四条同种一起养。同属鱼通常温和；条件相近的小型平和上层鱼有助于减少紧张感。其他鳅类须先确认攻击性和领域性，不能因同样住在底部就默认适合混养。近亲可能吃卵或仔鱼，繁殖缸宜单独安排。
雌雄区分
成年雄鱼胸鳍较大，第七、八鳍条加粗并融合为板状结构；雌鱼通常较大而厚实。
补充说明
它曾以 Lepidocephalichthys cf. hasselti 或 Lepidocephalus cf. thermalis 出售，但可能属于尚未描述的种，LE1 代号不应被当作正式学名。眼下棘受惊时可竖起，捞鱼需防挂网。

Overview
Lepidocephalichthys sp. 'LE1', sometimes sold as the Vietnamese marbled hog-faced loach, has no confirmed species identification. Fine sand, companions of its own kind, and a quiet aquarium are the main practical requirements; a trade label does not establish its identity as a described relative.
Distribution & habitat
Vietnam is the recorded country of origin. Collection near Da Nang in central Vietnam has been suggested but remains unconfirmed. Its actual habitat is unknown. Relatives commonly occupy shallow slow channels, swamps, oxbows, backwaters, and rice fields with mud, sediment, submerged roots, or leaves, sometimes changing substantially with the seasons. This is comparative guidance for the aquarium.
Aquarium setup
Provide a footprint of at least about 45 × 30 cm and soft fine sand. Fish spend time buried, sometimes showing only their eyes. Coarse gravel risks injury and stress and may interfere with feeding. Place smooth stones, wood, and roots securely before adding substrate so digging cannot undermine them.
Subdued light, modest leaf litter, and several shaded refuges suit the display. Use gentle circulation with adequate oxygenation. Shield filter intakes from small fish and fit a secure lid.
Diet & feeding
Members of the genus generally sift substrate for insect larvae, small crustaceans, and similar prey. Offer suitably small sinking dry food together with regular live or frozen Daphnia, brine shrimp, and bloodworms. Check that hidden fish actually receive food.
Behaviour & compatibility
Keep at least four conspecifics. The genus is generally peaceful, and calm small fish using the upper water under similar conditions can reduce nervousness. Assess other loaches for aggression and territorial behavior before mixing them. Possible egg or fry predation by relatives makes a separate breeding setup prudent.
Sexual dimorphism
Mature males have enlarged pectoral fins, with the seventh and eighth rays thickened and fused into a plate. Females usually grow larger and appear fuller-bodied.
Notes
Labels such as Lepidocephalichthys cf. hasselti and Lepidocephalus cf. thermalis have been used, but the fish may be undescribed. LE1 remains a provisional designation. Movable spines beneath the eyes can catch in nets when the fish is stressed.
