Daniel, Unless they are in a tank of 200 gallons or more you are inviting problems, especially from rotting vegetation - and the leaves will rot. Unless you gravel clean with every water change, bottom stagnation might cause a slight build up of hydrogen sulfide gas. There won't be enough to kill you fish probably, but it sure won't do them any good. A small pump and sponge filter is cheap insurance. It gets rid of the nitrogen waste & circulates the water, too.
