I have 3 angel fish in my tank, and lately one of them has been hiding, not really eating, and not swimming as often as he used to, I looked at him close up just now and his eyes are kinda of bulging. The other two angel fish's eyes are like that but not as bad..Anybody know if the eye thing is normal or is this the problem do you think. My tank is still cycling, but since the first i got him he has been just fine. Help please
