Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais (total) : 12 - 13; Espinhos anais: 0; Raios anais : 8. Head width less than 1.8 times in head length; head length more than 1.3 times in body depth; body depth less than 3.6 times in standard length; eye diameter more than 1.3 times in interorbital width; dark green; often with an extended, soft abdomen.
Occurs over muddy, sandy and rocky substrates all over the lake, preferably in water of no more than 3 m depth. Is a real macrophytivore: specimens smaller than 15 cm feed mainly on zooplankton and insect larvae; macrophytes increase in importance with size and finally make up most of the diet (Ref. 35835).
