Épines dorsales (Total): 14 - 17; Rayons mous dorsaux (Total): 9-12; Épines anales 3; Rayons mous anaux: 8 - 9. Diagnosis: 12-17 rakers on lower limb of first arch; 27-30 scales in lateral line; generally with black spots and blotches on head and body (Ref. 81260).

Biologie     Glossaire (ex. epibenthic)

Estuarine species, preferring brackish water but found in freshwater during low tide (Ref. 68431). Male mouthbrooder (Ref. 41581). No marked sexual dichromatism when sexually active; forms temporary pair-bonds during reproduction (Ref. 81260).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Males carry eggs (Ref. 41581). Males of Sarotherodon nigripinnis dolloi construct nest and incubate eggs (Ref. 55074). Incubatory period lasts about 14 days; female retrieves newly released young in mouth (Ref. 72506). Juveniles become independant after about 4 weeks (Ref. 55074).
