Biology
Occupies floodplain pools in Sudd. Feeds on mud, vegetable debris and small invertebrates. Affinities: only to P. adspersus, morphologically similar; distinguished through scales on caudal peduncle, dorsal and anal fin rays and body coloration. Generates electric organ discharge of short duration that seems to correlate with aggregative behavior of the species. During the breeding season, males build nests and while patrolling their territory sporadically emit EODs at a mean rate of 18 Hz. Participating females, on the other hand, discharge at a fairly regular rate and this has been shown to play a role in sex recognition during courtship and spawning. Male and female EOD waveforms also differ in the amplitude ratio of the first and third phase. Also produce natural sounds
