Before buying new fish you need to treat the old ones.  When  looking for an effective ick medicine try to find products  containing  Malachite Green or Chelated Copper  Sulfate, which can treat your water for up to a month. 
If you worry about the cost of another tank then try looking at your local classifieds you can usually pick up a 10gallon for around 10 dollars.
