概述
波氏歧须鮠（Synodontis polli）生活在坦噶尼喀湖较深的泥底区域，强光下没有藏身处会不自在。它与多种近亲外形相似，挑选时尤其要核对较大的体侧斑点与较长头部。
分布与栖息地
确认分布为坦噶尼喀湖，在布隆迪、刚果民主共和国和赞比亚一侧均有记录，常成大群生活于约 30–125 米深处。姆韦鲁湖的记录尚未确认。
饲养环境
可参考 90 × 30 × 30 厘米，按坦湖硬水环境布置。石堆形成多个洞穴，另留开阔游动处；弱光更合适，若整体照明较亮，就必须提供充分遮蔽。
食性与喂食
可接受活饵、冷冻饵和干粮。与许多同属鱼不同，它通常拒绝大部分植物材料，不能把黄瓜、豌豆等当作一定能吃的主要补充。
习性与混养
可与体形合适、适应相同水质的硬水慈鲷、彩虹鱼或卵胎生鱼搭配，避免小到可能被当食物的伙伴。同种可以群养，初期建立地盘时可能出现争执，应给足洞穴与空间。
雌雄区分
成熟雌鱼腹部较圆。相比大型近亲，它体形较小，观察生殖乳突分性别较困难，宜结合成熟体态判断。
繁殖
野外为散卵型，繁殖时有明显配对现象。不能把这种野外配对观察直接理解成已有完整水族箱繁殖方法。
补充说明
贸易中可能以其他歧须鮠名称销售。岩歧须鮠（Synodontis petricola）是容易混淆的近似鱼之一，本种头部更长、体斑通常更大。

Overview
A catfish of deeper muddy areas in Lake Tanganyika, Synodontis polli needs shade and secure shelter in an aquarium. Larger body spots and a longer head help distinguish it from some similar traded species.
Distribution & habitat
Confirmed records are from Lake Tanganyika, including localities in Burundi, the Democratic Republic of Congo, and Zambia. Large schools inhabit muddy bottoms at about 30–125 m depth. Occurrence in Lake Mweru remains unconfirmed.
Aquarium setup
A 90 by 30 by 30 cm aquarium is the maintenance reference. Arrange rock caves within a Tanganyikan hard-water setup, preserving open swimming space. Dim light is preferable; brighter aquaria need especially generous shaded cover.
Diet & feeding
Live, frozen, and dry foods are accepted. Unlike many relatives, it refuses most vegetable matter, so peas or cucumber should not be assumed to provide a dependable dietary component.
Behaviour & compatibility
Appropriately sized hard-water cichlids, rainbowfish, or livebearers are potential companions when water requirements match. Exclude very small fish. Conspecific groups can work, with initial disputes expected as territories are established.
Sexual dimorphism
Mature females are rounder through the abdomen. Compared with larger congeners, its size makes genital inspection difficult, so adult body form is a more practical initial clue.
Breeding
Wild fish scatter eggs and show distinct pairing during reproduction. That observation does not provide a complete captive spawning protocol.
Notes
It can be sold under other Synodontis names. Compared with S. petricola, this fish typically has larger spots and a longer head, useful clues when checking an identification.
