Etymology: Nanochromis: Latin, nannus = small + Greek, chromis = a fish, perhaps a perch (Ref. 45335); wickleri: Named for Wolfgang Wickler in recognition of his behavioral studies of cichlids in general and of benthic Congolese cichlids in particular (Ref. 57505).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
Africa: Lake Mai Ndombe (= Lake Leopold II) (middle Congo River basin) in Democratic Republic of the Congo (Ref. 57505).

Morphology | Morphometrics
(total): 16 - 17;
soft rays: 8;
Vertebrae: 28. A large deep-bodied species of Nanochromis with an elevated soft dorsal fin ray count (10-11) and the presence, in adults, of strongly produced membranous fin lappets on the second and third dorsal fin spines (Ref. 57505). It has also an almost scaleless cheek and nape, an upper lateral line contiguous with the dorsal fin base, five laterosensory pores on the dentary, a tubular pore canal in the anguloarticular, and seven laterosensory pores on the preopecle (Ref. 57505). Snout long with a steeply inclined and strongly convex dorsal contour and an almost straight ventral contour (Ref. 57505). Lower pharyngeal jaw is extremely gracile, with narrow horns and a short blunt keel; the dentigerous surface is sparsely covered with fine weakly bicuspid teeth (Ref. 57505). Caudal fin longer than deep, subacuminate, with fin rays increasing in length from the outer rays towards the central rays (Ref. 57505).
Collected at sandy beach interspersed with flat laterite terraces; 1-2 m deep (Ref. 57505).
