Long dorsal and anal fins; pectoral fins short, not reaching anus (Ref. 55060). Pelvic fins drawn out into a long filament in mature males; genital papilla in both sexes small and flanged (Ref. 2). Coloration: In alcohol: Females and sexually inactive males: 2 rows of dark spots on sides, one at middle and one above upper lateral line (Ref. 4967, 55060). Basic melanin pattern very strongly marked; horizontal and vertical bands usually represented by intense black blotches, which may be contiguous (Ref. 2). Indications of about 7 vertical black bars across lower horizontal band; anal and pelvics and ventral surface of body dark grey; Tilapia-mark an oval black spot near hind end of dorsal fin (Ref. 55060). Blotch on top of caudal peduncle usually well-marked (Ref. 2, 55060).
