Etymology: Haplochromis: Greek, Haploos = single + Greek, chromis = a fish, perhaps a perch (Ref. 45335); fischeri: Named for G.A. Fischer, one the first Europeans with a deep interest in natural sciences to visit the area, assembling vast collections of plants, animals and other natural objects and undertaking fundamental studies to produce accurate maps (Ref. 79882).

背棘 (总数) : 15 - 16; 背的软条 (总数) : 8 - 10; 臀棘: 3; 臀鳍软条: 7 - 10; 脊椎骨: 29. Diagnosis: relatively small species, moderately elongate (body depth 2.6-3.0 times in SL); dorsal head profile relatively steep, strongly convex dorsally of large eye (eye diameter about 4.0 times in HL, 1.2 times in snout length and 0.96 times in interorbital space); lips moderately but more or less equally thickened; outer teeth strong with recurved tips, procumbent, especially in lower jaw; usually anteriorly 3-6 rows of inner teeth in upper jaw, rows not very distinct; haplochromine "head mask" very weakly developed, hardly visible in not sexually active males; dominant males bluish with greenish hue; prominent dark grey longitudinal band from eye to caudal peduncle, interrupted above anterior half of anal fin; second dark grey longitudinal band along upper lateral line; 6-8 weakly expressed vertical bars about width of iris may be present in live and preserved fish (Ref. 79882).
Found over sandy substrate, interspersed with patches of shelter which can be rocks or vegetation; especially common over exposed sandy beaches; feeds on gastropods, insect larvae, diatoms and copepoda (Ref. 79882).
