If your Mollies smell then you are not looking after their water properly. The basic rules for keeping fish healthy are :- 1 inch of fish needs a minimum of 1 gallon of water :- every tank needs a cycled filter running permanently :- every tank needs to have at least 50% of its water changed every week. If you are missing out on any of the above your fish will not last long.
