Then enlighten me please, what content makes prepared food so (more) valuable? Most fish don't eat fish and all those added stabilizers in nature. If you chose one of the specialised food you have only spirulina, only daphnia, only artemia etc. And the living form of that is always better than the dead one.
Yes and that comment just bolsters my argument, because ideally you wood feed live mice to your cat every day. But we don't for ethics and convenience. Ever heard of raw feeding?
Big fish eat smaller fish all the time, often including their own eggs and young.
What makes the high quality foods (not all commercial foods are the same) more valuable is that they are balanced with whole fish, shrimp, krill, kelp, etc., and fortified with vitamins and minerals. You simply don't have the diversity of live foods in your backyard to provide a balanced diet. For the same reason, ideally you would not simply feed your cat live rodents.
I am aware of the raw foodist movement, vegetarian, vegan, juicing, etc....
There are more diets than you can shake a stick at. My daughter has a vegetarian friend that was recently diagnosed as being malnourished. She wasn't eating enough different vegetables to stay healthy.
As I said in a previous post....each to his/her own. I realize that I won't convince you, but my post is for the benefit of those that may be on the fence regarding live vs. prepared. Our objective for our fishy friends should be to provide a balanced, nutritious diet.
