Haha u trying to pump your angelfish so that they grow faster??!!

If you feed like that make sure there's a daily regular feeding time or else almost can guarantee dropsy. When they are accustommed to the feeding time, their metabolism will automatically starts. Just like us when we don't eat at regular hours we get gastric (just for comparison not meaning the fish will get gastric).

Yeah angelfish can be cute little angles begging.......all the time. Refrain from the temptation to overfeed them.
