When we talk about freshwater angelfish, their aggressive nature while eating should be considered foremost to make sure that equal share of fish foods are shared during feeding time by all fishes in the water tank.
Since they are aggressive eaters by behavior, they will move to the top of the water tank while watching you, approaching them. Also, angelfish would want to feed almost all varieties of food ranging from flakes to live foods.
You should always handle angelfish with great care as they are very curious and territorial about their environment. So, be cautious and consider all these points in your mind while setting up tank and aquarium for your angelfish.
