概述

贵州爬岩鳅(Beaufortia kweichowensis)常以“蝴蝶鳅”等名称销售,贴石体形不代表能靠缸内残饵长期生活。成熟藻膜、清洁富氧的水和足够觅食空间,比把它当作除藻工具更重要。

分布与栖息地

原生中国南部珠江水系的西江流域,包括贵州、广西和广东。典型同属栖地为浅急流上游及支流,石质底床在充足光照和溶氧下形成丰富附着生物;部分主河道受污染影响。

饲养环境

底面积至少参考 60 × 30 厘米。砂砾底上铺不同大小的圆石,强过滤配合增氧、造流,每小时循环可参考水体的 10–15 倍。用较强照明培养藻膜,避免新沉木严重染水;附生植物和外露海绵也可提供觅食面。只放入成熟缸,定期部分换水,清理时保留多数表面附着物,并盖严防攀爬。

食性与喂食

天然食物可能以底栖藻类及伴生微生物为主。可给优质干粮、以蔬菜和螺旋藻为主的凝胶饲料,以及适量活冷冻饵;动物蛋白过多可能引发问题。优先提供硅藻、软绿藻,不指望它啃掉硬黑毛藻。藻量不足时另培长藻石轮换,瘦弱新鱼先减少食物竞争。

习性与混养

整体温和,但雄鱼会占据并守卫优质觅食地,驱赶其他雄鱼及相似鱼。建议六尾以上,雌鱼较常聚集在安静但有较强水流的位置;只有两三尾、尤其全雌时反而容易退缩。不要随意配金鱼,伙伴应适应同样的富氧流水。

雌雄区分

俯视时雌鱼较宽厚,吻与胸鳍轮廓较连贯;雄鱼较纤细,吻更方,胸鳍伸出角度更接近直角。

补充说明

商品名和近似种旧称容易混用,可结合体侧清晰斑点、偶鳍边缘及光滑下唇等核对,不凭“香港琵琶”等名称认种。

Overview

Often sold under broad butterfly-loach names, Beaufortia kweichowensis requires established grazing surfaces and clean, oxygen-rich moving water. Its clinging body form does not mean it can thrive indefinitely on leftovers or an exhausted coating of algae.

Distribution & habitat

Native to the Xi River system of the Pearl basin, it occurs in Guizhou, Guangxi, and Guangdong. Typical habitats of the genus are shallow rocky headwaters and tributaries with abundant surface growth. Pollution affects parts of the wider river system.

Aquarium setup

Start with at least a 60 by 30 cm footprint and a varied rocky surface over sand or gravel. Strong filtration, aeration, and current should support a turnover around 10–15 tank volumes per hour. Lighting encourages biofilm, while heavy staining from new wood is counterproductive. Established plants and exposed sponges add grazing area. Maintain a mature system, change water regularly, and secure the lid.

Diet & feeding

Likely natural foods are benthic algae and their associated organisms. Use suitable prepared foods, vegetable-rich gels, and moderate animal-food supplements without excessive protein. Diatoms and softer green algae are more useful than tough brush algae. Rotate separately cultured rocks if needed, and help emaciated arrivals recover without competitors.

Behaviour & compatibility

Males defend favorable feeding patches against other males and similar-looking fishes despite the species’ generally peaceful disposition. Groups of six or more reveal more natural behavior. Females often gather in quieter high-flow areas, and very small groups can become withdrawn. Choose current-adapted companions rather than goldfish.

Sexual dimorphism

From above, females are broader with a smoother transition from snout to pectorals. Males are slimmer, with a squarer snout and more angular pectoral origins.

Notes

Commercial labels and misapplied species names are common. Distinct body spots, paired-fin margins, and the smooth lower lip are more useful than a general trade name.
