Big Pond, you can also buy Purina Game Fish Chow which sells around here for about $11 per bag, not much different than dog food. I think it is about 32% protein and thus is formulated more for those who supplement the natural food their fish get. I've tried it and it made my fish fat and happy. The Aquamax is what fish farmers use since it can be the only food your fish get. I've heard it will grow them a little faster but I've used both and can't tell a difference.
