Purina is somewhat overpriced. But it is fairly consistant in its quality. Buy fish food based on the protein content not necessarily by the brand or price.

Just because I eat both cheap ground meat with fillers and T-bone steak doesn't mean I can't tell the difference or that one or both do not affect my overall health.
