Large angelfish are incredible to see as they are such a centerpiece in their environment. They require a lot of room to swim and essentially demand the whole territory as their own. In general, large angelfish shouldn't be kept with other angelfish due to their bold nature. They get along with most reef fish and in the right conditions, are easy to care for. Large angelfish graze the reef looking for algae, coral, and invertebrates, so they are not considered a reef safe fish.
