Adapted from Doadrio & Dominguez, 2004
Goodeidae are surprinsingly diverse in feeding habits:- Carnivorous - Herbivorous- Omnivorous- Or something in between.
It is thought that Characodon spp. may have trophic ontogeny.
A. robustus may have some herbivorous tendencies (Miguel Andrade, pers. comm.)
