概述
'Barbus' sublineatus 是西非分布广泛的河流鲤科鱼，适合有空间、富氧且有一定水流的群体饲养。不同河系的侧纹差异很大，可能包含多个近缘种，购买时不能只凭单一斑点数量判断身份。
分布与栖息地
分布从塞内加尔向东延伸至喀麦隆，涉及尼日尔河、沃尔特河、贝努埃河及多条西非沿海河流。记录国家包括几内亚、利比里亚、科特迪瓦、布基纳法索、加纳、多哥、贝宁、尼日利亚、马里和尼日尔等。
它似乎主要生活在河流与溪流中；广阔分布范围内的各类具体栖息地仍缺少同样详细的信息。
饲养环境
提供至少 120 × 30 cm 的缸底空间，维持干净、富氧的水和适度水流。偏深色底砂、光滑石块、根枝和水草结合良好照明，有助于显色。布景过于空旷时体色可能变淡。
食性与喂食
野外胃含物显示它是广食性的杂食鱼，摄食昆虫、其他无脊椎动物及水陆来源的植物物质。人工饲养可用含植物成分的优质干粮，搭配红虫、水蚤、丰年虾等活饵和冷冻饵，保持多样性。
习性与混养
至少 8–10 尾同养有助于减少紧张，并让等级互动集中在同种群体内。选择温和、体型相当且不会被它的活跃程度吓退的伙伴，避免过小的鱼。
雌雄区分
雄鱼预计会更鲜艳、纤细且略小；这一描述仍有不确定性，不宜仅据此给所有个体判性别。
补充说明
尼日尔河上游个体常有 3 处伸长深色侧斑，中游可能呈连续暗带，沃尔特河个体则可见 4 个斑点。这种差异及相似种的存在使鉴定不易。人工繁殖资料不足，不能把其他鲤科鱼的通用方法当成本种的验证记录。

Overview
Widespread across West Africa, 'Barbus' sublineatus is an active river barb suited to spacious group housing in clean, oxygenated water. Strong geographic variation in its flank markings raises the possibility of a species complex, so a simple spot count cannot reliably settle every identification.
Distribution & habitat
Records extend from Senegal eastward to Cameroon, through the Niger, Volta, Benue, and numerous coastal drainages. Guinea, Liberia, Côte d'Ivoire, Burkina Faso, Ghana, Togo, Benin, Nigeria, Mali, and Niger are among the countries represented.
Rivers and streams appear to be the main habitats. Detailed descriptions are not available for all parts of this extensive range.
Aquarium setup
Provide at least a 120 by 30 cm footprint. Maintain good oxygenation, clean conditions, and some flow. A darker substrate, smooth rocks, branching roots, and plants under good lighting encourage coloration. Fish can look washed out in extremely sparse surroundings.
Diet & feeding
Wild stomach contents establish a broad omnivorous diet of insects, other invertebrates, and plant matter from both land and water. Combine a quality vegetable-containing dry food with varied live or frozen bloodworms, water fleas, and brine shrimp.
Behaviour & compatibility
A group of eight to ten or more reduces nervousness and keeps much rank-related activity among conspecifics. Companions should be peaceful, comparable in size, and confident enough for an energetic neighbor. Avoid fish small enough to be regarded as food.
Sexual dimorphism
Males are expected to be brighter, slimmer, and slightly smaller. These are tentative tendencies, not a fully established identification method for every individual.
Notes
Upper Niger fish may carry three elongated flank patches, Middle Niger specimens a continuous stripe, and Volta fish four spots. Other similar species complicate identification further. Captive reproduction remains poorly documented; procedures borrowed from related cyprinids should not be presented as confirmed breeding records for this fish.
