You should be able to take it off if you need to. You will definately need a razor blade though. I have thought about doing the same thing many times, but I always had a can of black spray paint kicking around.
Just use slightly soapy water, spray the back of the tank, peel the backing off, slide it around and squeegee out the excess water, let it dry.
