If it is a major pet store like PetsMart or something they may take them but not to sell and they wont give you anything for your fish. If you go to a smaller locally owned store you have a better chance of your fish ending up in a good home and maybe of getting a trade for them (goods, other fish, ect.). I would try that, but if no store is willing to accept the fish you could try the internet trade centers for fish. I have ran across many online place to buy and sell guppies. You can do well selling fancy guppies online especially if they have good qualities like large tails, bright colors, things you find in well bred bloodlines. Good Luck.
