My molly has some sort of bacteria or fungus thing going on ( no one in this world seems to know what it is I've been to so many fish stores and there is literally no fish experts anywhere. So I bought melafix and pimafix and api general cure which is what I have been using in my 10 gallon hospital tank. Every time I give his dose of medicine within minutes, he swims to the complete bottom of the tank breathing oddly and stays there all day and the next day he will pop up and become active and eat. Is the medicine making it worse or why does he react poorly to medicine?!? Do I stop giving him medicine and if I do how will he ever get cured?? And if someone can please also figure out what the heck kind of disease or infection he has that would be great!
