Hi Suraksha,
  The symptoms you describe can all be attributed to the ich infestation.  It takes a couple of weeks for ich to clear up even though it might appear to be gone sooner. It is important to keep doing regular water changes as often as you can.  Changing 25% every day would not be too much if at all possible.  Basically the situation with ich is this: it is a nasty disease but it is treatable if you get the medicine in there soon enough. Once the medicine is in there it takes several days for it to work (this is because the ich parasite goes through various stages, only one of which is vulnerable to the medicine).  During that time, the fish gets quite a bit weaker and so it is really a race to see if the fish can outlast the dying parasites.
