I agree absolutely fish is very expensive, but they do take good care of their fish and they are of good quality. They are also pretty good when it comes to special orders.
Where is Fish Emporium?
Pet Shanty, Aquascapeonline (aquarium paradise), and shark aquarium are great spots too. If you are bored on a weekend go to aqascape or shark aquarium. A lot of times you can see stuff there you won't see anywhere else which is fun
