May we ask what brand of food were you referring? Although in my opinion, even saltwater food should be ok with freshwater.
Were you referring to this one?
If yes, I don't see anything wrong with using them for the freshwater although it is better to stick with what was designed for them.
i picked these up at the store in the cichlids section and didnt realize it was for saltwater fish until a few days later. i threw away my receipt so i couldnt return it. i have a tiger oscar, knifefish, jack dempsey, convict, blood parrot, and a pleco in the tank .. they wouldnt eat this anyways would they?
oh .. i didnt notice that in the link .. it says 'marine' on the can i have. i'm hesitant to put it in the tank because it has kelp and other things in it. i didnt know if it would change the waters chemistry i.e. add salt
