A pet store won't be able to take them due to disease risk to their stock, regardless of how healthy they are. You could advertise them as free to a good home on a buy and sell site. You can't just put them into a body of water as they wouldn't be used to it and would not survive. You don't necessarily have to keep them in a tank, even a large plastic box/ bucket would do.
