What about filtration...what are you using? Maybe add an airstone or something so more oxygen is getting to the water? What all did you add from you established tank?
Personally, I wouldn't add the salt. Have you been using any meds at all or just doing water changes? The water changes are what I would recomend. Unless you know for sure what the problem is I wouldn't use any meds. I knew I should of said what I thought from the start and I am really, really sorry I didn't.
Here is what I would do if it were me. Set up the tank (which you did) use filter media from established tank, add decor..rock, or anything I could from the established tank. Up the temp a few degrees, do not add salt, do not add meds (the only time I have used melifex was for sores on the body or fin damage and it worked wonderful). Feed very lightly like once a day. Do 30-40% water changes daily for a few days and go from there. OMG, I am soooooo sorry I didn't voice my opinion sooner, but everyone seemed to be (and was btw) giving you such good advice and I am still somewhat new at fish care (as far as meds goes) I was worried I'd tell you something wrong.
As far as the salt goes, I wouldn't add it to the tank as a normal thing. Cichlids are not salt water fish and really do not need it. I know many ppl and many LFS will tell you to add it...but it is really not needed.
