| Примечания | Prefers sandy bottoms but also found in rocky to muddy bottoms. Zones with vegetation in calm waters provide shelter to larvae and young (Ref. 1456). Sexual dimorphism: females larger than males (Ref. 5160). Diet directly related with its length (Ref. 4726): pelagic larvae are zooplanktivores (Ref. 1456), juveniles feed on planktonic crustaceans and insect larvae found among vegetation (Ref. 11250), adults feed mainly on smaller fish species (Alestes, Micralestes, Tilapia oreochromis, Haplochromis and shrimps (Ref. 11249). Variability of prey species is directly related to the flooding season. |
