Fish Food, McDonald's Equivalent
I work at a "big box" pet store, and I explain this to every customer this way. Feeding your pet "grocery store" brand (a brand, outside of a very select few, that can be purchased at the grocery store) is like feeding your pet McDonalds for every meal. If you are going to spend your money anywhere, it best be on the food, everything else comes second.
So my question is, is the brand Tetra like the McDonald's of big name brands?
I personally give my fish an array of food types and textures.
