Etymology: Parananochromis: Greek, para = the side of + Latin, nannus = small + Greek, chromis = a fish, perhaps a perch (Ref. 45335). More on author: Boulenger.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; pH range: 6.0 - ? ; dH range: ? - 2. Tropical; 23°C - 25°C (Ref. 2060)
Africa: drainages of the Lokundje, Nyong, Ntem and Dja (Cameroon) (Ref. 81260). Also in the Ntem system in Gabon (Ref. 81260) and Equatorial Guinea (Ref. 5673). Restricted to forested areas (Ref. 5673).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm SL male/unsexed; (Ref. 81260)
(total): 14 - 16;
soft rays: 6 - 8. Diagnosis: lachrymal plus four tubular infraorbitals; slight gap between third and fourth tubular infraorbital; snout rounded; soft dorsal and anal fins, and caudal fin usually densely marked with vertically aligned rows of maculae in both sexes, those on caudal fin coalesced and usually forming a series of vertical bands (Ref. 81260).
Monogamous, biparental, substrate spawner displaying some degree of sexual dichromatism (Ref. 81260). Pair-bonding, cave spawner (Ref. 52307).
