Great advice from Nudist. As far as the food, were you advised that it's the "best" by the pet store, or did you do some research first? Remember, these pet stores are the same places that will tell you a tortoise can live in a 10 gallon tank its whole life and tell you that corn-based crap diets are the best for your cat and dog, so take everything you hear in a pet store with a grain of salt, no matter how knowledgeable the employee seems.
