Answer: Fish food varies. Whether or not you want a high-protein food, or a low-protein food. And this varies because you have to evaluate what you’re trying to do with fish food. Are you trying to simply feed fish? Or are you trying to grow fish? For example, in a recreational lake, you may want to have a high-protein food for big bass if you’re trying to trophy fish or commercial fish where you have people come in and pay to fish your ponds. So we recommend different, there are different names of fish foods. Purina makes a PondMax food; there are different names, but it’s mainly based on protein.
