Africa: Niger to Congo River basins (Ref. 3203). Widespread in the Congo basin (Ref. 1878, 4910, 11970, 41580, 41591, 106245, 106290). Also reported from Lake Tanganyika (Ref. 114071). Report from the Cuanza in Angola (Ref. 99599) unconfirmed in Ref. 120641. Reports from Lake Kivu are erroneous (Ref. 46152, 107916).
非洲: 尼日到剛果河流域。 在十字河流域與 Chari 上游中,在 Ogun 中，僅限於尼日下游了。

Occurs close to the bottom where it probes for food with the long snout. Territorial and usually aggressive towards members of its own species. This behavior has been shown to involve electric organ discharge (EOD) activity (Ref. 10011). Feeds mostly at night on worms and insects (Ref. 7020), probably aided by electro-sensory inputs (Ref. 10011). Electroreceptors are distributed over the entire head, the dorsal and ventral regions of the body, but absent from the side and the caudal peduncle where the electric organ is located (Ref. 10011). Sex-related EOD characteristics in this species has been demonstrated in the laboratory with freshly imported samples during the breeding season; such EOD dimorphism changed with time in captivity (Ref. 10764; 10766). Lead nitrate in water significantly increased EOD rate and selectively altered the EOD waveform of this species (Ref. 10469). Dubbed a `hearing specialist' having auditory abilities in the range of 100-2500 Hz, with `best frequencies' between 300 and 600 Hz (Ref. 10830). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 150 cm; not recommended for home aquariums (Ref. 51539).
生存于接近底部在哪里它探查食物以长的吻尖。 具有领域性而且通常对同种的其他鱼具有侵略性。 这行为已经被显示包括发电器放电 (EOD) 活动。 (参考文献 10011) 大部份在晚上捕食蠕虫与昆虫 (参考文献 7020), 可能藉由发电-知觉的输入的帮助。 (参考文献 10011) 电感受体被布满整个头, 背部与身体的腹面区域, 但是发电器官所在的体侧与尾梗没有出现.(参考文献 10011) 这种的与性别有相关的 EOD 特性已经在繁殖季节的时候在实验室被新输入的样本实验证明; 如此的 EOD 同种二形随着时间改变在繁殖场了 (参考文献 10764; 10766)。 在水的硝酸铅重要地增加了 EOD 率而且选择性地改变了这种的 EOD 波形。 (参考文献 10469) 被授予称号了听证会专家' 有听觉的能力在 100-2500个赫兹的范围中, 具有在 300 与 600Hz 之间的最好频率.(参考文献 10830) 水族馆保持: 形成 5个或更多个体的群体; 水族馆最小体型 150 公分; 不为家庭的水族箱鱼推荐。 (参考文献 51539)
