Malachite Green is a general treatment for most of your common tank diseases.

It sounds to me that you're describing a good case of Ick. Follow the directions on the bottle and put up the temp in your aquarium a few degrees. If this continues for another few weeks seek further information.

You really can't do any harm in the above treatment. They usually say repeat the treatment twice.

Have a look at my article on fish disease for a brief overview of Ick.
