I don't know what happening to my gourami, these days she's not energetic and there's a small black swelling on her belly. Is that any kind of sickness? Please help me

I have two zebra danios that have white lumps on their lips. I have been treating it with microbe-lift artemiss (natural expellant for bacterial diseases) for 10 days but it doesnt seem to be getting any better. The fish are still lively and running about the tank. I just want to get this...
