Here are my spots I hit often, with the first one being my favorite
Aquatics and Exotics - My number one spot, the owners name is Jason. He has a 17,000 gallon shark tank, freshwater stingrays and a Fly River Turtle, all of which were mine besides the shark.

Gerbers Saltwater Warehouse - They also have a TON of freshwater - Bring your checkbook because they can be pricey but you can talk them down.

Jacks Pets - They have stores all over, some are good, some are so so, some trade in fish and some dont so its a hit and miss. Know your fish when you go there because they dont label all of their fish and dont know what some are so you may get a good deal.
