Distressed gourami

Question
Hi, saw your profile and don't know if you can answer since it looks like you deal with cichlid fish usually, but here's my situation:  
 
Have a long-finned Red-skirt Tetra that wasn't eating very well, looked pale and like it might be getting a bit of cloudy eye or maybe pop eye on Tues (2/9), so did a 25% water change that night then put some Maracyn II in the next morning.  Upon getting up Thurs morning (2/11) to feed and reapply meds, noticed that the Tetra looked a little better, but now my Dwarf Gourami seemed to be swollen.  Upon getting home from work Thurs evening, the Gourami was definitely bloated and seemed a bit pine-coney as well (dropsy, I'm assuming).  So I did another water change (about 20% this time) and this morning (Fri 2/12) these are my water stats - Nitrate 10, Nitrite 0, Ph 7.5, Kh 40, Gh 60, Ammonia 0.  Gourami still swollen this morning, although he still eats and swims around, and I'm not sure what my next course of action should be.  I do use aquarium salt regularly and replace it with every water change as per directions.  
 
So I guess my question is:  Could the Maracyn II have caused the swelling in the Gourami and should I continue the treatment or switch to something else, if anything at all?
 
Sorry for so long a post, but just wanted to give you all the information I could.  Poor little guy looks miserable and I don't want to make him worse...  Thanks for any help you can offer

Answer
Hi Tammy,
 Unfortunately that is really hard to say.  Doing the water changes is good.  BTW, I never use aquarium salt.  Your fish (gouramis and tetras) come from water with NO salt content so I cannot see any advantage to adding salt to the water.  

 The problem with things like Maracyn II is that they are very strong and often cause as many problems as they cure, so I am reluctant to use them unless absolutely necessary.
