Wow I just got a bag last friday. Any idea of why they are shutting down? I really hate to hear this, I feed 2 ponds daily with their food and the growth rate was tremendous. What is the best food that is like Optimal Blue gill? I have used Purina Aquamax but it is about 30 dollars a bag more expensive here and it is a pain to get it. Great thing about Optimal is that they ship it to your door! Free! If I had know they were closing I would have ordered 6 bags.
