概述
斑马鸭嘴油鲶（Brachyplatystoma tigrinum）以奶油色底上的清楚细暗纹和成年仍保留的尾丝见长。它需要高溶氧、强水流和极大空间，贸易幼鱼常从秘鲁采集，不能把幼鱼来自小水道理解为成体也适合小型静水缸。
分布与栖息地
分布于巴西、哥伦比亚和秘鲁的亚马孙上游，模式地点是巴西马德拉河急瀑水段。成鱼似乎依赖主河道，常在白水急流和瀑流水段；秘鲁伊基托斯附近的小支流则会采到幼鱼，部分先在商业设施养大后出口。
饲养环境
以极大型设施为前提，砂底、大型沉木或简洁裸缸比精细草景适合。灯光不宜过亮，巨大且可靠的过滤、充分水流与增氧缺一不可；每周部分换水 50%–70%，严格控制水质。设施规划必须把长养空间和维护能力一并计算。
食性与喂食
天然几乎以水中捕获的小鱼为食，多数个体能接受虾、贝肉、鱿鱼和鱼肉条等非活饵。成鱼每周最多一餐，不需天天投喂。
习性与混养
伙伴必须足够大而不会被吞食，同时能适应相同的强流、高溶氧条件。
繁殖
野外在旱季末开始繁殖，早期生长阶段集中于六月至十一月。它似乎不像某些近亲那样需要横跨整个亚马孙的迁徙，但这不等于已有可照做的缸内繁殖方案。
补充说明
与朱鲁短平口鲶（Brachyplatystoma juruense）相比，斑纹更清楚、体形较修长、须也更长。幼鱼侧面斑点逐渐发展成成年条纹，不能只按幼鱼一时花纹判断。

Overview
Defined dark bands, a pale cream ground color, and persistent adult tail filaments mark Brachyplatystoma tigrinum. Strong circulation, high oxygen, and exceptional space are central requirements. Juvenile collection from small channels does not establish similar adult needs.
Distribution & habitat
The upper Amazon range includes Brazil, Colombia, and Peru, with a Madeira cataract as the type locality. Adults appear tied to main channels, often around whitewater rapids and cataracts. Young fish are collected from smaller tributaries around Iquitos and may be grown on before export.
Aquarium setup
Plan around a very large facility. Sand, substantial wood, or a simple bare arrangement is more practical than delicate planting. Keep light restrained and provide powerful dependable filtration, abundant movement, and high oxygenation. Weekly changes of 50–70% are recommended, so the maintenance burden matters as much as space.
Diet & feeding
Small fish caught in the water column dominate the natural diet. Most individuals adapt to suitable nonliving shrimp, shellfish, squid, and fish pieces. Adults need at most a weekly meal.
Behaviour & compatibility
Companions must both escape swallowing and tolerate the same demanding water conditions.
Breeding
Natural spawning starts near the close of the dry season, with early growth from June through November. A basin-wide Amazon migration does not appear to be part of its cycle, but that does not establish an aquarium breeding method.
Notes
Compared with Brachyplatystoma juruense, it has sharper markings, a more slender body, and longer barbels. Juvenile flank spots develop into adult bands, so identification must account for growth.
