well, my boyfriend and myself had just recently started a community freshwater fish tank. we had done a lot of research on what fish can and can't go together. so we went into the store and bought some fish for our tank. tested the water to make sure it was good before putting the fish in, we were good to go! we bought 3 of each kind of fish..total we had 12 fish. put them in the tank after following the half-@$$ directions we got from the employee at the store and by the next morning ALL 12 FISH WERE DEAD!! I can't explain how upset I was. if you want fish, go to Rick's fish and pet supply in Frederick..it Aquatic Creations in Urban.
