All types of Angelfish need an abundance of oxygen in the water but bubblers are not required. There are more methods for producing oxygen in the water such as using filters. If you are keeping an internal powerhead filter, then make sure you point the nozzle of the filter towards the water surface. When a filter breaks the water surface, gas exchange takes place that adds oxygen from the air in the water & gets rid of CO2. SUMP, Canister & Hang on Back filters are located outside aquariums, & then send water back to the aquarium using an outlet hose. Water flows back to the aquarium using a free fall method that disturbs the water surface & allows gas exchange to take place. Sponge filter needs an air pump for operation, & when these bubbles reach the water surface, they break the surface & allow gas exchange to take place. There is no need to setup an air pump & an air stone in the Angelfish aquarium if you have a filter.
