ການຈະເລີນເຕັມໄວ: Lm 9.6, range 10 - 12 cm
Max length : 17.7 cm SL ຕົວຜູ້/ບໍ່ມີເພດ; (Ref. 34290)
ຄີ (ໜາມ)ແຂງຢູ່ຫຼັງປາ (ທັງໝົດ) : 1; ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ) : 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).
Body shape (shape guide): fusiform / normal.
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).
Oviparous (Ref. 205). Distinct pairing during breeding (Ref. 205).
