With two adult angelfish, you'd be slightly "over" the recommended capacity. Of course, that is also influenced by how often you do water changes, your filter type, and the distribution of decorations/plants (swimming room). Some folks will also note that angelifish should be kept in groups of 3-5. My opinion on that is it sometimes depends on the temperament of the individual angelfish! I have one male that is so aggressive I cannot keep him with any other angels. That being said, angelfish do naturally school, and as cichlids, you are going to have aggressive interactions between angelfish - that's just their nature. Two angels, unless they happen to be male & female and form a pair, are likely to have aggression issues. If you like a peaceful tank, I'd recommend against just two angels in the tank.
