So a little background, I am new to saltwater tanks. Hell I am really new to fish. However I am interested in doing my own food for the fish. I currently make my own raw dog food so I have quite a bit of experience preparing animal food. I understand each fish will have its own dietary needs. With that said, why do most people add liquid vitamins to their fish food as opposed to using the fish's organs, which are considered the most nutritious part of the animal. The organs commonly are very vitamin and mineral dense. I am just wondering if there is a reason to not use the organs. Thanks for the info in advance :)
