In Lake Kyoga abundant among or near water lilies (Ref. 49805) and in Lake Victoria it occurs in shallow, inshore waters over sandy and rocky shores (Ref. 4903, 97924), seasonally over muddy bottoms adjacent to papyrus swamps or deep water near rocky islands (Ref. 9606, 97924). Feeds on bottom and in marginal vegetation; insectivorous (chironomid larvae, Povilla, Odonata larvae), but arthropods, oligochaetes and fish eggs are also eaten (Ref. 12526). Uses sensitive pointed addition to chin for testing holes in mud, papyrus roots and between stones to locate underwater insects (Ref. 36900). Rotates body to almost vertical position, searches substrate and grabs prey into mouth; produces weak electric organ discharge for navigation and to warn off other organisms (Ref. 97924). Oviparous (Ref. 205). Breeds twice a year during the rainy seasons, and migrates up rivers to spawn (Ref. 10608).
出现于在沙质与岩石底部上的沿岸浅水区水域,出现季节性地在泥沙底上面邻近广泛的纸草沼泽。 在岩石的岛附近, 也发现于深水域。 吃大的 libellulid 蛹与其他的大猎物。 (参考文献 9606) 卵生的.(参考文献 205) 在河上面回游产卵.(参考文献 10608)

Bayesian length-weight: a=0.01318 (0.00612 - 0.02839), b=2.85 (2.67 - 3.03), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
