I didn't think it was normal to lose that many fish.
I have lost:
5 guppies
6 platies
8 mollies (Balloon, Black, Marble and Dalmatian)
2 ottos
2 Gouramis
I test the Ammonia, Nitrate, Nitrite and pH weekly and everything is normal and safe. The last new fish that I added into the tank was in June. I have 9 more fish in my 1 gallon hospital tank (that's the only available tank that I have) because they're looking very thin.

I treated the whole tank with Jungle Parasite Clear a few times since some of the fish were thin before they died. I really have no idea why my fish are dying at these incredible rates!
