Aquatic & Exotic, Inc Sold me a salt water fish and they put it in fresh water Stuart Florida

My husband and I were new customers and we went into their store Monday and purchased an ell and a filter, we didnt have a single problem with this order and we were so excited to go back on Thursday to purchase some fish that we had fell in love with. On Thursday, my husband went into their store and purchased 2 salt water fish and cleaner shrimp. After 2 hours we lost one fish and rushed to save the other and the shrimp. After getting the fish and shrimp into our tank, we tested the water that both fish and the shrimp came in. Turns out they were in FRESH WATER!!! Are you serious? FRESH WATER and SALT WATER FISH DONT MIX! The second we realized that the fish were in fresh water, of course this was after hours. So my husband spoke with the owner this morning and he will only give us a 25% off our next fish.. Seriously? 25% off when we just lost a $50 fish because of an error by YOUR EMPLOYEE??? That's sad. We can order fish online for less and still have a 14 day guarantee and you can't even guarantee that your fish will make it to our tank? Pathetic. We still have the dead fish and water it came in and they wont even look at it. This is just bad business all around. Go somewhere else and stay away from these guys. They are crooks.
