Fish ID - petsmart

I was at local petsmart a week ago, getting supplies for my new 5 gallon tank. When passing by the cichlid corner, i saw small grey and yellow fish with vertical stripes going down there sides in the 1-2 inch range. At first my original thought was multi's, however there were yellow fish in the tank that were almost identical to the grey fish. When i tried to get a closer look the tag with species info was gone. Any idea what these fish are?
