Taking them to where they came from is out of the question unfortunately. I do however know two areas that I'm positive grays can be found at. One is at a local park that has a lake, but I'm not comfortable taking them there because there is surrounding farmland that could pose a risk for pesticide or herbicide poisoning. The same applies to the other area I know that grays can be found. I'm not exactly fond of releasing them in those areas because of that.

As for Petco, there aren't any stores in this area so options for new aquariums are limited to Petsmart, Walmart, and two local pet stores.
