Balloon Molly With Fungus?

[slschmid]

I came back from my vacation and realized that my balloon molly was rocking side to side, when i looked closer she was covered in these grey/ translucent fungus like spots. Does anyone know what this is? I lost my other molly this way about 6 months ago id really like to find out how to fix it! Any suggestions?

To me it sounds like fungus! I've seen it on a dead fish before at a pet store. 
You can try "API Melafix for aquariums". I'm sure it will work. Not 100% sure though, you'll have to take time to look into the medication. my fish never got sick before so I've never used any medication
