A synthesis on the feeding flexibility in freshwater teleosts concerning seasonal, spatial, ontogenetic, individual and behavioral variation of freshwater teleosts is provided. The occurrence of a flexible diet is a striking aspect of tropical riverine ichthyofauna where most species may switch from a food item to another as soon as the relative abundance of the feeding resource in use oscillates, motivated by seasonal and spatial environmental alterations. There is a trophical change in almost all species during ontogeny, whereas in most populations, individuals may show feeding preferences or make use of distinct feeding tactics that lead towards a differentiated intraspecific foraging. These considerations highlight the difficulty on setting up reliable specific species feeding patterns in tropical teleosts
