Help me please

This topic will be hashed back and forth with no clear way to do the right thing. How about all the fish that get prayed on as food in the wild or in your tank for that matter. I would like to give this option and it certanly will not get me any karma. Big ones eat the little ones little ones got to be fast. Feed to another fish to keep it healthy. You know that is what happens in nature. I have learned that with all the love, care and research that I do for my fish it is not a place that is as peaceful as it looks from the outside of the glass.
