概述
雀斑鳞头鳅（Lepidocephalichthys cf. irrorata）保留近似种标记，身份仍需谨慎。作为辨认参照，名义种体形很小，头顶有较大外露鳞片，尾鳍带暗色网纹；不能把所有相似小鳅直接定为同种。
分布与栖息地
名义种记录涉及孟加拉国及印度东北部，包括曼尼普尔谷地的湖泊、溪流和洛克塔克湖。该湖有由植物、土壤和有机碎屑组成的漂浮植被垫，坝体及营养污染改变了水体环境。近似种的实际产地仍需结合采集信息确认。
饲养环境
饲养可参考至少 45 × 30 厘米底面积，细软沙底配稳固石木、阴影和落叶，便于钻藏。粗砾可能影响取食或损伤身体，硬景先固定再铺沙。避开强流而保持增氧，防止小鱼钻入过滤入口，并盖好缸。
食性与喂食
可尝试细小下沉干粮，规律供应水蚤、丰年虾、红虫等适口活冷冻饵。筛砂取食小动物是可能的天然方式，不作为已确认的完整食性结论。
习性与混养
可参考同属至少四尾的群养安排，并选择同环境、温和的中上层小鱼。其他钻沙鳅先核对性格，避免好斗或强领地者；卵和幼鱼可能被取食。
雌雄区分
可参照名义种成熟雄鱼胸鳍增大、内侧鳍条融合增厚的特征，雌鱼一般更大、更厚实；这些线索不能代替种级鉴定。

Overview
The “cf.” designation in Lepidocephalichthys cf. irrorata retains uncertainty about identification. The nominal species offers a comparison through its small size, large exposed head scales, and dark tail reticulation, rather than an automatic identification for every similar fish.
Distribution & habitat
Records for the nominal species include Bangladesh and northeastern India, including lakes and streams of the Manipur Valley and Loktak Lake. Floating vegetation-and-soil masses are a distinctive feature there, while impoundment and nutrient pollution have altered the lake. Actual provenance remains important for this unresolved form.
Aquarium setup
As a starting arrangement, provide at least a 45 by 30 cm base with soft sand, stable hardscape, shaded retreats, and leaves. Avoid coarse substrate that may interfere with burial or feeding. Secure decoration before sand, maintain oxygen without strong flow, protect filter intakes, and cover the aquarium.
Diet & feeding
Try small sinking prepared food while supplying regular suitable live or frozen invertebrates. Substrate sifting for tiny prey is a probable feeding pattern rather than a confirmed complete dietary account for this unresolved form.
Behaviour & compatibility
Genus-level guidance suggests at least four together with quiet open-water fishes from compatible conditions. Assess other loaches individually for territoriality, and consider possible predation on eggs or fry.
Sexual dimorphism
The nominal species is described with enlarged male pectorals and fused thickened inner rays, while females tend to be larger and fuller-bodied. Such sexing clues do not resolve species identity.
