I would assume you need to give some test results of the water parameters before anyone can answer that.

Sam, If you want to just keep the fish most tap water is fine after 24 hrs of storage and aeration in a contaner of some type. If what you get out of the tap is pure RO you may need to add some minerals back. The only way to know is to go to your local fish store and get a test kit that measures kH, gH, and pH. Do the tests and let us know the results.
