Maturity: Lm ? range ? - ? cm
Max length : 8.2 cm SL macho / no sexado; (Ref. 47153); 7.6 cm SL (female)
Espinas dorsales (total): 15 - 16; Radios blandos dorsales (total): 8-10; Espinas anales 3; Radios blandos anales: 7 - 10; Vértebra: 29 - 32. Small, slender, laterally compressed body (Ref. 47153). A rather acutely pointed snout (Ref. 47153). Lips slightly thickened (Ref. 47153). Lower jaw ventral outline almost straight, the rostral outline of lower jaw straight or slightly convex with a smoothly rounded mental area (Ref. 47153). Pectoral fins just reaching the anus; dorsal fin rays slightly longer than those of the anal fin, nearly reaching the caudal fin base (Ref. 47153). All scales on the head are cycloid; scales on rostral part of dorsum cycloid or very weakly ctenoid, caudal part of dorsum with ctenoid scales; scales on flank and caudal peduncle ctenoid; ventral chest scales small and cycloid, lateral chest scales moderately small, weakly ctenoid (Ref. 47153).Live basic color for males is bluish-grey dorsally and silvery white ventrally, sexually active males have a pitch black head and body; females and juveniles have a distinct, relatively thin mid lateral band, but the cheek of the females are slightly more greyish (Ref. 47153). Two continuous longitudinal bands on the body (Ref. 47153).
Haplochromis thereuterion occurs in the upper layers of the water column in Lake Victoria (Ref. 47153).
