So I am new to this forum, not new to aquariums. I just noticed these white spots on one of my angel fish fins. There are 3 angels in the tank but only the one has them. He doesn't seem to be bothered by them, he doesn't scratch or anything like that and he is eating regularly. But it does make me worry because I don't want it to be something that can hurt him or any of the other fish and me not try to fix it immediately. TiA
