Fish Issues

Question
I have had my 29 gallon tank for about two years now. I have not had any big problems but this past week has been stressful for my fish. I have a blue Gourami, 2 danios, a mollie that I raised and 3 recently bought mollies, a platy that I raised and 2 recently bought platies. About a few days after I bought my 2 new platies and 3 new mollies, I noticed white spots on one of my 2 platies that I raised (but is now deceased). I immediatly thought of Ich and did some research. I bought Ich treatment tablets and followed the directions specifically. A few days later my now deceased platy died but his sister remains alive but she still has white spots. About a day after the death I noticed some of my mollies eyes were getting cloudy. Could this be from the treatment or is it something else? My Gourami has a red discolortion by his mouth and I don't know what it is. My danios are acting strange, they are breathing heavily and one looks to be somewhat bloated. I did some research and I found that this could be due to high temperatures and I have noticed a higher change in temperature. And to top it all off my female molly that I bought recently had her 13 babies. I knew she was pregnant but I was surprised when I found them because of all the things that were happening and she could have had them early because of all the stress.

I am pretty desperate here. This week has been pretty stressful for me and the fish. Can you recommend anything? Thanks,

Answer
Jess,
at this point for lack of a better term you have nuclear tank syndrome going on.
A series of issues each compounding the other.
The quick courser of action is to do a 50% water change, add some Zeolite to remove the ammonia, then discard it.
do a smaller water change in a day, like 5 gal.
Add some bacteria supplement to aid the biofilter, don;t over feed and drop the temp back to where it should be, around 78 or so.
If you don;t have a freshwater test kit, get one that will test PH, ammonia, nitrite and nitrate.
Be wary of products that offer you the quick fix-all, that particular product does not exist.
Good luck
