概述
眼斑歧须鮠（Synodontis ocellifer）是较强健的中大型鲶鱼，脂鳍很长，可作为辨认线索。成长后可能略有领域意识，但通常不如一些近亲强烈；成鱼体形仍使它不适合普通小鱼社区缸。
分布与栖息地
分布记录包括尼日利亚、冈比亚、乍得、喀麦隆、塞内加尔、马里、加纳、尼日尔和几内亚，多见于溪流及回水环境。
饲养环境
可参考 90 × 30 × 30 厘米的空间。柔软底床上以岩石、沉木和弯曲根枝形成躲藏处，浮水植物帮助柔化光线。其他植物有益但非必需，若养多尾，应让每尾都有可占用的庇护所。
食性与喂食
可按同属的多样化喂食建议，活饵、冷冻饵、干粮与去皮豌豆、黄瓜等植物材料搭配。不要让鲶鱼长期只吃其他鱼留下的残食。
习性与混养
避免体形小到可能被当作食物的伙伴，可选择体形相称、强健而不过分好斗的鱼。成熟后对其他歧须鮠可能更护地盘，足够大的缸和各自藏身处有利于小群共存。
雌雄区分
成熟雌鱼明显更丰满。生殖乳突检查也可辅助判断，但处理时容易被尖锐背鳍棘刺伤，不宜随意抓握翻腹。
繁殖
野外在季节性淹水、微生物丰富的地方散卵，没有亲鱼照顾。商业鱼场曾借助激素完成繁殖，这与普通水族箱内自然繁殖是不同情形，不应把有售幼鱼当成家庭繁殖容易的证明。
补充说明
相似种及杂交个体都可能出现在贸易中，核对身份时不宜只凭斑点。脂鳍很长是线索之一，但仍应结合其他形态观察。

Overview
A robust medium-to-large catfish, Synodontis ocellifer has an unusually long adipose fin. Territorial behavior may develop with age, generally less strongly than in some relatives, but its adult size still rules out a routine small-fish community.
Distribution & habitat
Records extend across several West and Central African countries, including Nigeria, Gambia, Chad, Cameroon, Senegal, Mali, Ghana, Niger, and Guinea. Streams and backwaters are typical habitats.
Aquarium setup
A 90 by 30 by 30 cm aquarium is the maintenance reference. Soft substrate with rocks, wood, and roots supplies retreats, and floating plants diffuse the light. Additional vegetation is optional. Multiple fish need sufficient room and a separate refuge for each.
Diet & feeding
The genus-level feeding approach combines live, frozen, and dry foods with plant matter such as shelled peas or cucumber. Provide deliberate meals instead of assuming leftovers meet its needs.
Behaviour & compatibility
Exclude fishes small enough to be considered prey. Robust, appropriately sized companions are better candidates. Mature fish may defend space against related catfishes, but a small group can work when the aquarium is large enough and each individual has a retreat.
Sexual dimorphism
Mature females are much fuller-bodied. Genital-papilla inspection can assist sexing, although sharp dorsal spines make casual handling unsuitable.
Breeding
Wild spawning occurs in seasonally flooded, microorganism-rich areas, with scattered eggs and no parental care. Commercial production has used hormones, which does not demonstrate that natural spawning is straightforward in a home aquarium.
Notes
Lookalikes and hybrids can appear in trade. The long adipose fin is useful, but spotting and a sales label alone are insufficient for confirming identity.
