White fluffy near gills on pleco

Hi there I recently brought a pleco at the time of them catching it because I didn't have my glasses it had 3 defects that didn't look normal to me "I maybe wrong" it's fins had like a torn or sore on the end of one of them also noticed it had white fluffy bits near its gills and the most common one was white spot which was very easy to check when I let the bag float in the tank when i got home. I have a few chemicals for diseases but not sure which it would be for I've got.
Pimafix, disease clear,white spot and parasite.
Which one would I use for this white fluff.

Any help would be great thanks!.
