It sounds like your fish may be ill, but why don't you post a photo of it and get a general consensus on what's wrong before you start medicating and possibly harming your fish? Generally, if it is ich, a little salt and elevated temp. is all you need to take care of it. It sounds like you're getting a little frenzied... don't worry, it happens to me too. We just need to look at the whole scope of the problem, instead of in little pieces of information, and then pick what to do next.
