In Gainesville there is Aquatropics and Ocean Exotics. The first has some good corals for pretty good deals, but their fish usually look sick. And the second has pretty good fish, but not too many great corals and their prices are a little high.
In Ocala there's Aqualinks and Tanks-A-Lot. I haven't been to either, but I hear Aqualinks is better, and Tanks-A-Lot really isn't worth going to.
And I hear Fish and Other Ichthy Stuff is really good too, but might be too far out of your way.
You're not taking 75 all the way right? You'd miss Orlando. Well anyway, I also heard that Aquarium Fanatics, Sea in the City, and Aquaria Studio are decent too. Of course WWC will make all their corals look dull. lol.
