概述
印斑歧须鮠（Synodontis notatus）会长成较大的鲶鱼，白天比许多近亲更活跃，也常在中层游动。它对同种攻击明显，除非空间很大，一般只养一尾，不适合普通小型社区缸。
分布与栖息地
分布于刚果民主共和国和刚果共和国的多种河流环境。
饲养环境
可参考 120 × 30 × 30 厘米的空间。柔软底床配岩石、沉木与根枝形成藏身处，浮水植物帮助减弱照明。其他水草可用但不是必需，应为它保留中层活动和穿行空间。
食性与喂食
可参考同属杂食性的投喂安排，活饵、冷冻饵和干粮搭配去皮豌豆、黄瓜等植物材料。成鱼体形较大，混养中的小鱼仍有被当食物的风险。
习性与混养
适合体形相称、较强健的伙伴，不要放能被吞下的小鱼。成熟后可能更有领地意识，尤其针对其他歧须鮠；对同种尤为不友好。白天较活跃不等于需要持续受到其他鱼骚扰。
雌雄区分
成熟雌鱼明显更丰满。生殖乳突也可用于判断，但检查需要处理尖锐背鳍棘，不能把普通手持翻腹当作无风险分性步骤。
繁殖
野外在季节性淹水、微生物丰富的区域散卵，不护卵也不护幼。不能仅凭商业繁育计划的传闻，把人工繁殖当作稳定成熟的方法。
补充说明
不同地区个体可能有三、六、十二个斑点，甚至无斑，所以“一点”商品名并不适用于每尾鱼。近似种也可能混入同批销售，核对时应结合整体形态而非只数斑点。

Overview
A sizable catfish, Synodontis notatus is more active by day than many relatives and often swims in midwater. Strong aggression toward conspecifics makes a single individual the usual choice unless the aquarium is very large.
Distribution & habitat
It occurs in several river habitat types in the Democratic Republic of Congo and the Republic of Congo.
Aquarium setup
A 120 by 30 by 30 cm aquarium is the stated reference. Use soft substrate, rocks, wood, and branching roots to form retreats, with floating plants softening the light. Additional planting is optional; retain swimming room through and above the shelters.
Diet & feeding
Genus-level feeding advice supports varied live, frozen, and prepared foods with vegetable material. Its adult size also means tiny companions cannot be assumed safe from predation.
Behaviour & compatibility
Choose robust, appropriately sized companions and exclude very small fish. Territorial behavior may strengthen with maturity, especially toward related catfishes, and aggression toward conspecifics is pronounced. Daytime activity does not remove the need for secure retreats.
Sexual dimorphism
Mature females are markedly fuller-bodied. Genital-papilla examination offers another method, but sharp fin spines make casual handling inappropriate.
Breeding
Wild fish scatter eggs in seasonally flooded areas rich in microscopic life and provide no parental care. Reports of commercial breeding projects do not establish a reliable home-aquarium method.
Notes
Regional forms can have several spots or none, making one-spot labels unreliable as a literal diagnosis. Similar species are also mixed in trade; use the overall appearance rather than spot count alone.
