Just looking for some opinions on feeding live food. Does this make the fish more or less aggressive? I know to watch out for bacteria and what not. I have a fairly aggressive tank, oscars, jag, jd, gt, salvini, lyonsi, are some of my more aggressive fish. They're all gettin along great and I don't want to feed them live and have them turn on eachothers. If you could please share your opinions and stories, good / bad. Thanks, Eddie
