Aquarium Paradise is good, they know thier stuff, but tend to be pricy for not so great quality (aquariumparadise.com) . Blue Sierra is great. The Fish Store in Seattle is really good. they have better corals in the winter when its not to expensive to ship them. I have heard good things about Midway. The lakewood ***** is a place I go when i stop at Aquarium Paradise. They are the best *****. Corals arent that great, but their fish are very decent. If you come out to Gig harbor, there is Pets and Pals. I work there :O). We have good prices and fish but not that much as far as quantity (because its a pet store as well as fish...) We are also really good at special orders.
I hope this helps. If anyone else has any others, Im always interested.
