My understanding is that Oscar's are at best primarily, carnivorous cichlid's. I doubt they would accept such food's. But you're correct, there's no harm in trying some vegetable matter in their diet. I offer my cichlid's frozen peas and the odd bit of zuchini on the odd occasion, but had never thought of friut's. I was reading the sticky thread about diet in the Pleco forum, which is where i got the idea of offering my Pleco some fruit. As someone stated in this thread, they regularly eat fruit which has fallen from over hanging branches, i suppose omnivorous cichlid's would also. Learn something new everyday.
