So my angel has been in my tank for about 2 months and he has been fine. he is eating and swimming great with no signs of stress. today i came home to this white film on his body and eyes. it doesn't appear to be ich but i'm no professional. added a flame angel about a week ago that had been in the store for over a month with perfect health. no other fish are showing signs. should i put him in my qt tank right now or what? water test show perfect, no nitrates. can my flame angel infect the tank without showing signs? there are no spots just a fur/film on him and his eyes.
