Madison used to have a few stores but it's been a while. Surprising that they still can't support a good store there.I live about 10 minutes from saltwater aquarium stores. Are they good... no. Realistically, I live about an hour and a half from good ones. Thankfully Wisconsin has some very good coral suppliers and shipping for online orders is always easy.
I just wish Madison had some better aquarium stores in general.
In SE Michigan I've got quite a few to choose between, and the one I frequent the most is only a mile away.
