OK, I left to go to my grandmas for the holidays noon today. I checked the tanks, fed, etc. Then, I come home and one of my guppies has white spots all over her fins. Only her fins and not on her body. What is this? She's is like scratching herself at the bottom of the tank (wiggling/swimming but in place). Or is this a bacterial infection? Every other fish looks fine, just her.
What is this?
