I have a pregnate Platy, and I noticed today she has white globs on her side fin and shes not looking very good at all. I medicated the tank with Furan - 2 , I followed the directions ! I medicated the whole tank because one of my other females died a few days ago. But she didn't have any signs of being sick same with a male I lost yesterday morning.
The water, I teseted and everything is normal. Any suggestions would really be apprecited ! Thanks
