Now that I getting into saltwater tanks, and eventually going to want a big tank with a mini-reef, with all the filtration that goes on for the big ones (skimmer, sump, canister, etc...) How much do store owners have to invest to have all of the tanks (fresh and saltwater), fish, inverts, rock, filtration (which I would personally like to go back and see at a store), and inventory to sell products. Give a ballpark figure on how much you think it costs. Do stores start out small and build up? And I'm not talking about like Petco and stores like that, just your basic local fish store.*BOUNCINGS
