概述
头条波鱼（Rasbora cephalotaenia）适合大型温和混养缸，体侧暗带由一串斑点组成，而不是连续实线。它活动量不小，对成熟水质的依赖比造景形式更重要，在茶色水中体色尤其明显。
分布与栖息地
见于马来半岛、苏门答腊、婆罗洲和泰国南部；新加坡原生种群被认为已局部消失，中国旧记录很可能误认。栖息泥炭沼泽林的黑水溪河，林冠遮光，落叶和枝条丰富，水极软且可很酸。种植园扩张和开发持续影响这类栖地。
饲养环境
群养约需 120 × 45 × 45 厘米。细沙、沉木、干落叶和浮水植物能形成遮荫，耐弱光水草可作点缀；落叶表面微生物也能为幼鱼补充食物。维持偏暗照明和稳定水质，不要放入尚未成熟的新缸。天然栖地极低酸碱度并不意味着饲养必须追求极端值；缓慢适应与日常维护更关键，缸盖须防跳。
食性与喂食
可能主要摄食水生及陆生无脊椎动物。可用优质适口干粮配合红虫、水蚤、丰年虾等活饵或冷冻饵料，保持食谱多样。
习性与混养
至少 6 条同养，足够同伴可减少紧张。可搭配体型相当且温和的波鱼、鳅类或其他适应相同环境的鱼，黑水布置下还须核对伙伴的水质需求。
雌雄区分
成熟雌鱼腹部更圆，常略大于雄鱼。
繁殖
本种被描述为散卵且无护卵行为，但爱好者繁殖成功情况不明确。可尝试近缘种的隔卵繁殖方法：约 90 × 30 × 30 厘米浅缸、弱光和成熟水，调养后放入一两对，少量多次补较凉水。约两天后移出亲鱼，使用海绵过滤。属内常见孵化约 18～48 小时、再 24～48 小时平游只能作参考；先备微型食物，随后再增加活饵大小。

Overview
Rasbora cephalotaenia is an active, peaceful choice for a substantial aquarium. A chain of dark spots forms its lateral marking, helping distinguish it from relatives with a solid stripe. Established water conditions matter more than elaborate decoration, although tannin-colored water enhances its appearance.
Distribution & habitat
Native records span the Malay Peninsula, Sumatra, Borneo and southern Thailand. The former Singapore population is considered lost, while old Chinese records are probably erroneous. Forest peat-swamp channels provide shaded, very soft acidic water over accumulated leaves and wood. Habitat conversion threatens these environments.
Aquarium setup
A group needs roughly 120 by 45 by 45 cm. Sand, shaded woodwork, dried leaves and floating plants suit a forest-water display. Microorganisms on decomposing leaves can supplement fry food. Avoid biologically immature tanks and abrupt chemical changes. Extremely acidic habitat records are not a target that every aquarium must reproduce. Fit a close cover.
Diet & feeding
The presumed wild diet is largely small invertebrates. Combine suitable prepared food with regular live or frozen portions to maintain condition and color.
Behaviour & compatibility
Keep six or more to encourage confidence. Comparably sized peaceful fishes can share the aquarium, but a blackwater-themed community still requires matching each species to the actual conditions.
Sexual dimorphism
Females generally become fuller-bodied and somewhat larger at maturity.
Breeding
Hobby breeding success is uncertain. The fish is described as an egg scatterer without parental care, and a method adapted from relatives may be attempted in a dim, shallow 90 cm container with egg protection. Add conditioned pairs and introduce cooler water gradually. Remove adults after about two days and use sponge filtration. Genus-level development times are only approximate guidance; microscopic food should be available before larger fry food is introduced.
