Justification

This species has a wide enough distribution, with no known major widespread threats, to qualify as Least Concern. It has also been assessed regionally as Least Concern for north eastern Africa. It is only known from Lake Nasser with its North African distribution, and more survey work is needed to confirm the full extent of this species' distribution, and it is therefore categorized as Data Deficient in that region.

Inhabits both still and flowing waters, breeds in the flood season. Feeds on mollusks (Ref. 28714). Possesses electroreceptors over the entire head and on the ventral and dorsal regions of the body, but absent from the side and the caudal peduncle where the electric organ is located (Ref. 10011). Its electric organ discharge (EOD) is steroid-sensitive (Ref. 10763; 10764). Fecundity value of 18,924 eggs has been reported for this species (Ref. 10607).
