That's the best posted response I've seen to that question.Oddball;510164;510164 said:Grapes are OK now and then but not too regularly since the sugars can cause bacterial blooms in your tank. Pacus are ominivores that eat fruits, nuts, and plants in the wild. Some good choices for a regular diet inclusion are frozen peas, lima beans, corn, greenbeans, potato slices, diced apples/pears, etc. Infrequent offerings can include grapes, chunks of banana, pineapple, oranges, melons, etc.
