Etymology: congica: Referring to the origin of the type material of this species, the Congo Basin (Ref. 43912).

Environment: milieu / climate zone / profondeur / distribution range
Écologie
; eau douce démersal; pH range: 6.5 - 7.4; dH range: ? - 18. Tropical; 23°C - 26°C (Ref. 2060)

Taille / Poids / Âge
Maturité: Lm ? range ? - ? cm
Max length : 9.0 cm SL mâle / non sexé; (Ref. 43912)
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 0; Épines anales: 0; Rayons mous anaux: 65 - 93. Diagnosis: adipose fin always absent; inner side of pectoral spine without serrations (Ref. 43912).
Schooling species, confined to larger rivers; most active during the night (Ref. 43912). Feed mainly on aquatic and small terrestrial insects (Ref. 6868), insect larvae and small worms (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Maximum reported TL 100 mm (Ref. 43912). Of very little economic importance; occasionally this species has been exported for aquarist purposes (Ref. 43912).
