Etymology: Petrochromis: Latin, petra = stone + Greek, chromis = a fish, perhaps a perch (Ref. 45335); horii: Named in honour of M. Hori of Kyoto University, Japan; he suggested that this fish might represent an undescribed species (Ref. 95531).
Environment: milieu / climate zone / depth range / distribution range
; 淡水 底中水層性, usually 13 - 15 m (Ref. 95531).
Africa: Lake Tanganyika (Ref. 95531).

型態特徵 | 形態測量圖
背棘 (總數): 18 - 19; 背的軟條 (總數): 9-10; 臀棘 3; 臀鰭軟條: 7 - 8. Diagnosis: Petrochromis horii differs from its congeners with no overlaps in several morphological characters: its body is deeper than that of Petrochromis macrognathus; the caudal peduncle is deeper than that of P. orthognathus; the pectoral fin is longer than that of P. macrognathus; the pelvic fin is longer than that of P. fasciolatus; the caudal fin is longer than that of P. famula, P. fasciolatus and P. orthognathus; the interorbital region is wider than that of P. macrognathus and P. orthognathus; the upper jaw protrudes more than that of P. fasciolatus and less than that of P. macrognathus, P. polyodon and P. trewavasae; the soft rays in the dorsal fin are fewer than in P. macrognathus; and the number of scales in longitudinal line is larger than in P. famula and P. orthognathus (Ref. 95531).
Usually found on rocks (Ref. 95531).
