Ok, odd question, but I believe that many wild betta's natural habitat is the paddy field, yes? I know rice is different than wheat, but it's still a plant. Since the bugs that are a natural part of the betta's diet may eat those rice plants/grain, and since betta are not known for carefully removing the stomach content of their prey, then we must imagine that wilds betta are ingesting at least a tiny bit of grain in their lives. Probably not anywhere near the amount in many commercial foods, but still a bit.
Also, lets not forget that unless that rice is being raised in an "organic" fashion, then the farmers are likely using all manner of fertilizer, pesticide, and heaven knows what else on their fields. Granted, I would guess many of these practices started happening after the betta splendens was already being hybridized into our domestic fish, but even before that time I can't imagine that life in a paddy field would be considered easy or safe.
