Maximum observed length in Lake Kainji: 100 cm, observed weight: 10000 g (Ref. 3034, Ref. 3799). Young found in swampy places among aquatic vegetation (Ref. 5156, Ref. 30488); adults live in the open water of rivers and lakes, where they can be found in the pelagic zone as well as the littoral zone (Ref. 5156). Are able to survive in deoxygenated waters; the hardiness of this fish, together with its great growth rate make it a candidate for aquaculture in Africa and it has been transported to a number of countries for this purpose (Ref. 1739, Ref. 50623). Escapees from ponds into the wild resulted in established populations, which form the basis for fisheries (Ref. 1739). Are considered as mud-feeders (Ref. 6160), but in West Africa also as phytoplankton feeders (Ref. 3023, Ref. 31256). Feed mostly on plankton, being the only plankton-feeders of the Osteoglossidae (Ref. 13851). It has a suprabranchial organ which has a sensory function, but also a mechanic function in concentrating the little food particles (Ref. 3012, Ref. 50624). During breeding, mature adults create a circular nest in swamps (Ref. 13851, Ref. 26281, Ref. 41544). The young leave the nest after a few days and are guarded by the male (Ref. 26281).
