Hey, welcome!
The local shops are all a bit "lacking" in one way or another. For instance, at Gold you might find someone who knows something about corals and will give you a good price. At Wai's you may see nice SPS but nobody will speak to you. At Ocean you may find good prices but not many corals, and fish that may be kept for 2 weeks before selling. At Pisces you'll find a nice big store where (perhaps) many fish and corals perish, and prices seem quite high. But there is a good selection of captive-bred clowns...
I won't mention Big Al's.
So once you've been around to them all a few times, you get a feel for who is leading you straight (hopefully), but this only goes as far as their own knowledge, which is multiplied tenfold on this and other hobbiest sites and discussion boards. The accumulated knowledge and experience from the members here vastly outpaces the knowledge and experience of a few shopkeepers, but they are the "professionals" and sometimes take offense to this notion.
I've heard they have a reputable shop up in Edmonton, but haven't been to visit.
Cheers,
