Air bubbles do practically nothing to improve your water quality. The air pump should be attached to a filter to gain any real good from it. An angelfish needs a temperature of around 78F to 80F (It is a tropical fish). It also needs to be kept according to the basic rules of fish keeping and they are. :- 1 inch of fish needs a minimum of 1 gallon of water. (1 angelfish needs at least 10 gallons). :- Every tank needs a fully cycled filter running permanently. :- Every tank needs to have at least 50% of its water replaced every week. If you keep to those rules your fish stand a cance of surviving. If you don't, I can guarantee that you will have constant problems with the health of your fish.
