They are primarily, it just seems that my guy likes them!
I have a few omni's in my tank and they do love peas once or twice a week, and the Arowana just decided to try a floating one and now he seems to eat them!
I figure that it's fine for him because in the wild they will eat vegetation if it's accidentally caught during a strike for prey, as you say, they are primarily carnivores, but my guy seems to enjoy a pea so I don't argue with it! It's a sneaky source of extra vitamins!
