Query: be nice to your fish - use stress coat

yes, it's an added expense, but stress coat is very nice to have on hand for anytime you have a less than perfect situation in your tank; adding new fish, setting up a new tank, cleaning the old one or maybe the water quality got a tad bit too dirty before you changed it, or maybe your fish got sick/ stress coat just helps to ease the stress on the fish. be nice to your fish, use tress coat.
