Scott dude, chill out. Do pet strores that sell dogs and cats take in every stray? no. if you have a car that you want to get rid of, does every dealer take in every car? No. If you ahve a computer you no longer want, do you take it to best buy (probably where you didn't buy it), and say "here take my computer, i'm done with it, but give me something back." No. So stores do take in trades on some fish. Some stores don't as a policey. I don't believe at all that is irresponsible for a store not to take fish, it is irresponsible of the owner to get that unwanted fish in the first place.
