My fish had a white cottony kind of fluff hanging on his gills...it was a pretty big chunk of stuff, and earlier when i did a water change i wiped some similar looking stuff off his floating log. i didnt see it anywhere else in the tank. after i took pictures i tapped the tank, and the fluff fell off (and he attempted to eat it). He still has a very tiny white patch on his gill on the other side. Should I be concerned about this, or is it likely just some yucky tank junk that got stuck to him? He's eating and acting fine,and otherwise looks fine.
