First, I'm a girl, so bugger off. Second, oh well, I don't care about feeding live animals to other live animals. That is to say, I don't like it in the whole 'oohh, look at the blood!' or anything like that, but I don't have a heart attack about it being wrong either. It's nature, and while yes, it is in captivity, who are you to say that the natural way of things is cruel? The whole point of keeping pets (at least it should be) is to re-create their natural habitat in the home so that we can enjoy them. The only reason we have dried food, flake food, and other things is because it is more convenient for us, not them. They are healthier eating live food (as long as it isn't diseased) as this is they way they were built. I'm am not, however, going to waste anymore of my time defending this idea, because there will always be people that think I am wrong, and the thing is, I don't care. Do what you want. If your friend is feeding live mice to his arrowana, so be it.
