I noticed last night that one of my cardinal tetras had cotton wool like substance near his head last night. I thought that I would go and get some meds today but unfortunately it died during the night. When I had a look at it close up I could not see the cotton wool like growth on it and wondered if some of the other fish could have nibbled at it (yuk!) Should I treat the tank in case any of the other fish get it?
