Angelfish like most fish using their gills. Most fish have a very basic circulatory system due to their having only two valves in their hearts which only pump one way. The blood pumps to the gills where it bonds with the oxygen in the water which then carries it through the body to be used and around it goes back to the heart to start the process over.
Angelfish have gills that extract oxygen from water. Without water, they would suffocate and die.
Angelfish breathe the same way any fish breathes. They take in water through their gills and take in the oxygen in the water and release the water.
