well, you have uncle bills (2 stores), the reef, and a few others that are decent but I forget the names. If you're going to be slightly north of indy the best stores (IMO) are in marion. Picture Perfect is my favorite. They take excellent care of their fish (some tanks are even RO). Art in motion is good for the bread and butter fish, they have decent prices as well.
I think the indy stores are WAY overpriced, but they're fun to look at and have a good selection. When are you going to be in the area?
