生態學
; 淡水 底中水層性; 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 / 年齡
Maturity: Lm 9.6, range 10 - 12 cm
Max length : 17.7 cm SL 雄魚/尚未辨別雌雄; (Ref. 34290)
背棘 (總數): 1; 背的軟條 (總數): 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個下顎齒。 上頜骨觸鬚在一些標本中幾乎到腹鰭的起源而且在其它裡面幾乎到肱骨突起的到頂端。 外部的顎觸鬚有細長的分支, 內部的對有短的, 但是細長的分支。 大理石花紋的土黃色 (大理石紋非常可變, 一些個體全身褐色的).(參考文獻 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).
棲息於湖 (參考文獻 4967) 但是狀似較常見於河超過在湖中.(參考文獻 34291) 吃軟體動物與昆蟲。 (參考文獻 13624) 昆蟲, 特別地寶刀魚仔魚與 Povilla, 是在食性中是優勢的。 (參考文獻 34291) 卵生的.(參考文獻 205) 很少對長度大於 15 公分 SL 生長。 (參考文獻 34290)

Bayesian length-weight: a=0.01549 (0.00700 - 0.03427), b=2.88 (2.70 - 3.06), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
