Habitat and Ecology:
Habitat and Ecology
Occurs in shallow waters over both sandy and rocky habitats and appearing seasonally over muddy bottoms adjacent to extensive Papyrus swamps. Also found in deep water near rocky islands. Feeds on large libellulid nymphs and other large prey (Okedi 1971) (after Froese and Pauly 2003). Originally common in shallow inshore waters over both sand and rock (Lake Victoria), and in or near water lilies (Lake Kyoga), before introduction of Nile perch and Nile tilapia became fully established in the two lakes. Now rarely encountered. Max. size: 36.0 cm SL.
