I am from St. Louis myself and not quite sure what Petco FishOrBust went to but I have 3 Petcos within 10 miles of me (the are about 15 in Metro St. Louis) and 2 of them have very knowledgeable staff. One of them has the best set up of aquarium displays I have ever seen! The other one I saw I could care less about. Like what RDD said it depends on the manager of the store and how much care he puts into how the store is ran. Petco is a little more pricier than Petsmart but when it comes to quality and knowledge you can't put a price on that!
