Resumo: 	This study investigated the feeding habits of Serrapinnus microdon and S. calliurus and possible seasonal differences (rainy and dry seasons) in the utilization of food. The fish were collected monthly in Cancela stream, in the basin of the Manso/Cuiabá rivers in the State of Mato Grosso, from March 2003 to February 2004. Both species preferentially consumed resources of autochthonous origin, independently of the season. The diet of S. microdon was basically composed by immature forms of aquatic insects, with Chironomidae and Ephemeroptera predominating during the entire study period, thus showing a restricted diet (Ba = 0.27 in the rainy season, and 0.29 in the dry season). For S. calliurus, aquatic insects (especially Ephemeroptera) were equally important, but algae and detritus were also prominent depending on the season, showing a less specialized diet (Ba = 0.44 in the rainy season, and Ba = 0.48 in the dry season). Both fish species presented a benthivorous feeding habit; however, everything indicates that they live together without competition, because the food on which they depend is widely available. Serrapinnus calliurus was susceptible to seasonal changes in the availability of food resources.
