-----Question-----
I have a 75 gallon tank and a pair of angel fish.  The tank is adeguately filtered but I have noticed one of my angel fish staying in a vertical orientation at the surface of the tank and at times sticking its mouth out of the water.  It is also breathing quite rapidly.  Any idea what is going on?
-----Answer-----
Hi Alex,
 Is it being bothered/chased/bitten by the other one?

Answer
Hi Alex,
 Sometimes the "bothering" occurs at night when most people aren't around, so that is a possibility.   Be sure that you have lots of structure (plants, wood, rock) in the tank to break up the space and give weaker fish a place to hide.
