“…Creagrutus guanes is an omnivore and generalist species that consumed high proportion of benthic fauna (mostly Diptera larvae), and allochtonous matter (mostly seeds). The diet of C. guanes is similar to the diet of other members of the genus Creagrutus (Ortaz, 1992(Ortaz, , 2001Román-Valencia, 1998), and other members of the order Characiformes, even from different habitats such as floodplain rivers (Ortaz, 1992;Esteves & Galletti Jr., 1995;Ortaz, 2001;Vilella et al, 2002;Barreto & Aranha, 2006). We conclude that the diet of C. guanes is not a rare case, but instead may represent the diet of many tropical freshwater fish.…”

“…Sin embargo, más que opuestos son complementarios, ya que su interpretación conjunta parece indicar que es una especie de alta plasticidad, dado que dispone del alimento presente en los diferentes ecosistemas que habita. Lo mismo ocurre con Poecilia reticulata que ha sido reportada como una especie insectívora (Machado-Allison 1987, Ortaz 1992. Ortaz (2001) la reporta como una especie herbívora ya que el 75 % de su dieta está constituida por microalgas.…”

“…O estudo dos hábitos alimentares de peixes, em rios tropicais, tem destacado a importância do material de origem alóctone, do perifiton e de macroinvertebrados bentônicos como alimento (ANGERMEIER; KARR, 1983;MOYLE;SENANAYAKE, 1984;POWER, 1984;ORTAZ, 1992;LOWE-McCONNELL, 1999). Em cabeceiras, o fluxo rápido da torrente impede o desenvolvimento de vegetação enraizada e do fitoplâncton, e a produção primária é realizada por algas e musgos que incrustam fundos rochosos .…”
