Large white patches

Question

Yellow Platy with spot   I've had this female platy about a year. Over the last week she has developed these white patches (not small like ich) on tail base, ridge of back and behind one eye. Seems a little lethargic. She is the only one.
Any ideas on what to do.
Thanks

Lisa,
It sounds like a fungal issues. There are many medications for this that work well. Make sure you follow the directions on the packaging. It is very important to keep their water very clean by testing their water and doing weekly water changes.
