生态学
; 淡水 底中水层性; pH range: 6.0 - 8.0; dH range: 5 - 25; 深度上下限 0 - 70 m (Ref. 34291), usually 0 - 30 m (Ref. 34291). 熱帶; 22°C - 26°C (Ref. 2060); 3°N - 5°S
Africa: Lakes Victoria, Nabugabo and Kyoga, affluent rivers of Lake Victoria, Victoria Nile (Ref. 4903). Also found in the Lake Rukwa drainage (Ref. 27292), the Malagarazi River (Ref. 54847, 98755) and the Middle Akagera system (Ref. 46152, 54979). Specimens from Kingani River (=Ruvu River) are misidentifications of S. orientalis (Ref. 78218).
非洲: 維多利亞湖，湖 Nabugabo 湖，維多利亞尼羅河， Kyoga 湖， Kagera 河， Ihema 湖, Kingani 河?, Malagarasi(尼羅河流域).
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 9.6, range 10 - 12 cm
Max length : 17.7 cm SL 雄鱼/尚未辨别雌雄; (Ref. 34290)
背棘 (总数): 1; 背的软条 (总数): 7. 32-54 mandibular teeth. Maxillary barbels reaching almost to the origin of the pelvic fin in some specimens and to the tip of the humeral process in others. Outer mandibular barbels with slender branches, inner pair with shorter, but slender branches. Marbled yellowish-brown (marbling is extremely variable, some individuals uniformly brown) (Ref. 34290).
32-54个下颚齿。 上颌骨触须在一些标本中几乎到腹鳍的起源而且在其它里面几乎到肱骨突起的到顶端。 外部的颚触须有细长的分支, 内部的对有短的, 但是细长的分支。 大理石花纹的土黄色 (大理石纹非常可变, 一些个体全身褐色的).(参考文献 34290)
Lives in streams and rivers and in lakes, where it prefers shore regions (Ref. 78218). More common in rivers than in lakes (Ref. 12526). Common in marginal vegetation of Kagera River (Ref. 4903). Replaces S. victoriae in shallow waters of Lake Victoria (Ref. 4903), prefers areas less than 20 m deep (Ref. 34290). Feeds on insects (Povilla and chironomid larvae) and molluscs (Ref. 12526). Oviparous (Ref. 205). Rarely grows to lengths greater than 15 cm SL (Ref. 34290).
栖息于湖 (参考文献 4967) 但是状似较常见于河超过在湖中.(参考文献 34291) 吃软件动物与昆虫。 (参考文献 13624) 昆虫, 特别地宝刀鱼仔鱼与 Povilla, 是在食性中是优势的。 (参考文献 34291) 卵生的.(参考文献 205) 很少对长度大于 15 公分 SL 生长。 (参考文献 34290)
